    Chemical notes on bonding Ionic bonding - This occurs between metals and non metals - Fe2+/3+, Cu+/2+, Zn2+, No3- - Metals loose electrons, non metals gain electrons. - Ionic compounds conduct electricity when dissolved, but not when solid, they also have high m & b points due to strong giant 3d lattice. They are also soluble in water as they have a charge - Metal atoms always form positive charged electrons while non metals from negatively charged electrons Metallic Bonding - They conduct

    molecules, which are formed by bonds, properties of life emerge. Bonds vary in type, with each having their own specific properties, effects and strengths. These varying types of bonds consist of: covalent, ionic and hydrogen. A covalent bond is the chemical bonding in which the attractive force between atoms is created by the sharing of electrons, resulting in the formation of a cell's molecules and is categorized into two subtypes, non-polar and polar. While a non-polar covalent bond involves the equal

    Chemical Bond: The attraction between two or more atoms to formulate a chemical substance, this bond is due to the electrostatic force of attraction between electrons of opposite charges, or this bond is due to a dipole attraction is called a chemical bond. Types of Bonds: The force of attraction as well as chemical properties in atoms or molecules of elements or compounds contrives three different types of chemical bonds. 1. Ionic Bonding: The bond which generates

    The second experiment is exothermic reactions because it gives out heat energy to the surrounding and energy is released more than it absorbed. It also has a negative energy change. In terms of bonds breaking or forming, the first experiment its forming new bonds, because when alcohols are burnt, the reaction is always overall exothermic. Because more energy is released when new bonds are form than is being consumed. If I compared my result to the literature values, are by no means accurate. But

    The purpose of this lab was to use what we know and have learned about evaporation, the molecular-kinetic theory of matter, and intermolecular forces to determine the relative strength of the intermolecular forces that exist between the molecules in six different types of liquids. This is important because chemists often need to rely on their understanding of intermolecular interactions to explain the bulk properties of matter. It will also help us understand the reason for many natural occurrences

    There are billions of people on this earth and each is unique in its own way. The same is true for molecules and substances. There are billions of different molecules and substances on earth and each one has unique properties to make it what it is. When looking at some of the smallest characteristics of things, molecular shape and intermolecular forces come into play. Molecular shape and intermolecular forces help determine what physical properties substances and objects have. Each plays a key

    thousands of rings of six atoms are covalently bonded together into long chains which form tiny tubes within the paper. The water molecule has been spilt leaving oxygen between each ring The long chains are held together by side-to-side hydrogen bonding(O-H) between the chains, so there is also weak dipole-dipole moment. These side by side long chains are called sheets of cellulose. The sheets are held one on top of the other by Van der Waals forces. The geometry of the short, carbon-hydrogen bonds

    Chemistry- Assignment 1: How does chemical bonding explain the properties of chemical and biological polymers? Introduction Until the early 1920 's, most chemists did not believe that the existence of molecules with a molecular weight that was greater than a few thousand to be possible as Reusch (2013) states. This view however was challenged by Hermann Staudinger in 1920. Staudinger was a chemist who studied natural compounds of which included rubber. His research in 1922 led to the idea that
