Atoms DBQ From a table to air, atoms make up everything. Atoms are in every liquid, solid, gas, and plasma. How has our research evolved since long ago? Over time, scientist have discovered different properties and structures through different ideas. An Atom includes protons, neutrons, and electrons. All of these have a different charge that is important to the structure. It has taken multiple decades for us to address the current day atom, which was first identified and then changed by crucial scientists.
To begin, the first idea of the atom was proposed by Leucippus and Democritus(doc 1). They suggested that matter is made of atoms. From then, the idea began to grow and become more accepted. However, this was just the beginning to the long road of discovery soon to come. It wasn't long before scientists were making more …show more content…

The beginning atomic structure was said to be a ball of electrons with scattered protons, this was called the plum pudding model created by J.J. Thompson (OI). The plum pudding model was the first atomic structure to be generally accepted by the scientific community. However, this model was disproved by the gold-foil experiment performed by Ernest Rutherford. The gold foil experiment was when a gold-foil sheet was collected and alpha particles(OI). The scientist expected the particles to go through the foil however, he was surprised to see the results. Some of the particles had bounced back off of the material while some went through like predicted. This is where the idea that atoms have a positively charged nucleus and consists of mostly empty space. This was the break though for the current atomic model. The current atom now consists of a charged nucleus containing protons and neutrons along with empty space(doc 2). This empty space involves a cloud of negative charged particles, called electrons(doc 3). Thanks to Rutherford, this is the atomic model we are guided by
