Answer 1

Answer:

Explanation will be answer.

Explanation:

Democritus thought if he cut something in half over and over again, it would stop at some point. He said that this last piece of material couldn't be cut smaller. Democritus called these little pieces of atoms of matter, which means "indivisible". He believed that atoms last forever, never change, and could not be destroyed. Democritus believed that there was nothing between atoms and that everything around us could be explained if we could understand how atoms work.

The plum pudding model is one of many historical and scientific models of the atom. The model was first proposed by JJ Thomson in 1904, shortly after the discovery of the electron but before the discovery of the atomic nucleus, and tried to explain two properties of the atoms known at the time: that the electrons are negatively charged particles and the atoms are not. You have a net electric charge. The plum pudding model has electrons that are surrounded by a positively charged volume, like negatively charged "plums" that are embedded in a positively charged pudding.

In 1920 Ernest Rutherford imagined the possible existence of the neutron. In particular, Rutherford examined the inequality between the atomic number of an atom and its atomic mass. His explanation for this was the existence of a neutrally charged particle in the atomic nucleus. He viewed the neutron as a double neutral conductor made up of an electron orbiting a proton.
