Chemical bonds are formed by the joining of two or more atoms. A chemical bond is a force that holds together the atoms in a molecule or compound. In chapter eight we learned the key concepts of chemical bonds and their properties. In this essay I will elaborate on the concepts we were taught and explain them in my own words. It will include the classification of different types of bonds, the bonding nature of both ionic and molecular compounds, and lastly I will explain how we predict the shapes of molecular compounds and polyatomic ions.
The classification of different types of bonds includes ionic and covalent bonds. Although there are more types of bonds such as coordinate covalent, network covalent, and metallic we focused mostly on covalent and ionic bonds. The classification of these different types of bonds is not a complicated concept. They are classified by what they bond with and whether they are polar or non polar. For example to classify a covalent bond as a covalent bond it would have to be a non-metal element plus another non-metal element. Same goes for an ionic bond but instead it would be a metal plus a non-metal element. Another way they are classified is if they share electrons or if they make a transfer of electrons.
When this lesson was first taught to me I didn’t really understand the difference between an ionic compound and an ionic bond same goes for covalent. I couldn’t distinguish them and understand them properly. Now I understand that an ionic bond is the bonding that exists in an ionic compound. I now understand the difference and just wanted to make a clarification.
The bonding nature of both ionic and molecular compounds will show that the materials produced tend to have many different properti...

...rmine and find out the shapes of molecular compounds and polyatomic ions. In the end I feel as if I understand the chapter more clearly now that I have analyzed the information and put it into my own words.
In conclusion, I’ve provided my insight and my understanding of chemical bonding in my own words. I have provided solid information and key concepts in order to make my statement clearer and more precise. I included the classification of different types of bonds, the bonding nature of both ionic and molecular compounds, and lastly I explained how we predict the shapes of molecular compounds and polyatomic ions. I may not know everything there is to know about chemical bonding. One thing I can tell you is that I know a lot more now that I have written this essay. It’s made everything easier to understand and gave me a better picture of what the chapter was about.
Unit 7: Chemical Reactions: Students will understand the basic concepts of reactions, bonding, the “mole” and how this relates to the law of conversion of matter.
In “The Fish” by Elizabeth Bishop, the narrator attempts to understand the relationship between humans and nature and finds herself concluding that they are intertwined due to humans’ underlying need to take away from nature, whether through the act of poetic imagination or through the exploitation and contamination of nature. Bishop’s view of nature changes from one where it is an unknown, mysterious, and fearful presence that is antagonistic, to one that characterizes nature as being resilient when faced against harm and often victimized by people. Mary Oliver’s poem also titled “The Fish” offers a response to Bishop’s idea that people are harming nature, by providing another reason as to why people are harming nature, which is due to how people are unable to view nature as something that exists and goes beyond the purpose of serving human needs and offers a different interpretation of the relationship between man and nature. Oliver believes that nature serves as subsidence for humans, both physically and spiritually. Unlike Bishop who finds peace through understanding her role in nature’s plight and acceptance at the merging between the natural and human worlds, Oliver finds that through the literal act of consuming nature can she obtain a form of empowerment that allows her to become one with nature.

Solid A was identified to be sodium chloride, solid B was identified to be sucrose, and Solid C was identified to be corn starch. Within the Information Chart – Mystery White Solid Lab there are results that distinguishes itself from the other 4 experimental results within each test. Such as: the high conductivity and high melting point of sodium chloride, and the iodine reaction of corn starch. Solid A is an ionic compound due to its high melting point and high electrical conductivity (7), within the Information Chart – Mystery White Solid Lab there is only one ionic compound which is sodium chloride, with the test results of Solid A, it can be concluded that is a sodium chloride. Solid B was identified as sucrose due to its low electrical
Images of medieval torture devices immediately spring into the mind with a mention of the words “cruel and unusual punishment”; however, this colorful, romanticized representation is a stereotype. One of the very first mentions of “cruel and unusual punishment” in Canada was in the Miller et al v. The Queen case of 1977. In this case reference to sections 1 and 2 of the pre-Charter Bill of Rights was applied (passive voice) in deciding that the death sentence for murder was indeed constitutional. A lasting influence of this case on section 12 of the Canadian Charter of Rights and Freedoms can be found in the decision that “‘cruel and unusual’ in s. 2(6) are to be read conjunctively
The book 1984, by George Orwell, shows us a what life would be like if nations such as Britain were under totalitarian rule. In particular, chapter nine of part two, Orwell would demonstrate how much control the Party, or government, has over the people through a sense of war and difference between social classes, which forces the people of Oceania to obey the Party. With the idea of war going on, it creates a fake sense of patriotism that makes the people of Oceania have the thought of hating the other nations and not the Party. The major differences in social standing, it makes the “proles”, or the poor working class, become exhausted and unable to think of a revolt. This leads to the argument of how war and social differences will help control
This chemistry book report is focus on a book called “Napoleon's buttons: How 17 molecules changed history” by Penny Le Couteur and Jay Burreson. The publisher of this book is Tarcher Putnam, the book was published in Canada on 2003 with 17 chapters (hey the number match the title of the book!) and a total of 378 pages. The genre of this book is nonfiction. “Napoleon's Buttons” contain a fascinating story of seventeen groups of molecules that have greatly changed the course of history and continuing affect the world we live in today. It also reveal the astonishing chemical connection among some unrelated events, for example: Chemistry caused New Amsterdamers to be renamed New Yorkers and one little accident of detonating cotton apron in a minor housekeeping mishap lead to the development of modern explosives and the founding of the movie industry.
The dotted lines shown on the picture are called hydrogen bonds. Each water molecule is bonded to four other molecules.
Neil Postman begins chapter 9 of his book Amusing Ourselves to Death: Public Discourse in the Age of Show Business, by discussing if politics is actually a spectator sport or if politics is just like the way show business is run. This chapter is titled ‘Reach out and Elect someone’, and Postman first writes about how politics is more like a "spectator sport" or, as Ronald Reagan put it, "like show business" (125).

Crystals can also be grouped as covalent, metallic, ionic and molecular crystals based on the physical and chemical properties. Covalent crystals have true bonds between all atoms in them. In metallic crystals, the individual metal atoms sit on lattice sites leaving the outer electrons free to float around the lattices. The atoms of ionic crystals are held together by electrostatic forces. A molecular crystal is held jointly by non-covalent interactions such as van der Waals forces or hydrogen bonding. Different crystals have different shapes and sizes which may be due to two factors: Internal symmetry
Bond enthalpy is the energy that is required to break a chemical bond. In most cases it is expressed in units of kJ mol-1, measured at 298 K. The most accurate/exact bond enthalpy of a particular chemical on is all dependant on the molecular environment in which the bond exists. The molar bond enthalpy is the energy required to break one mole of bonds between pairs of atoms in the 'gaseous molecule'. Bond enthalpy values are usually expressed in kJ mol-1 of bonds broken.
From these properties of bonds we will see that there are two fundamental types of bonds--covalent and ionic. Covalent bonding represents a situation of about equal sharing of the electrons between nuclei in the bond. Covalent bonds are formed between atoms of approximately equal electronegativity. Because each atom has near equal pull for the electrons in the bond, the electrons are not completely transferred from one atom to another. When the difference in electronegativity between the two atoms in a bond is large, the more electronegative atom can strip an electron off of the less electronegative one to form a negatively charged anion and a positively charged cation. The two ions are held together in an ionic bond because the oppositely charged ions attract each other as described by Coulomb's Law.
Bonds have a number of characteristics that differentiate one issue from another. We are going to define and describe a number of characteristics in detail below.
