The number of protons and electrons is equal on the periodic table
We NOW (currently) know that electrons move slowly on orbits around the nucleus.
What do we call our current model of the atom?
Who was the first to say that MATTER could be broken down into smaller parts; he gave the atom its name by saying the smallest particle is indivisible, or "Atomos".
Which scientist came up with the planetary model, which stated that electrons orbit the nucleus like planets and are arranged in a set pattern on energy shells according to their energy levels?
This scientist was credited for creating several laws regarding the atomic behavior and how atoms formed matter, such as "The Law of Conservation of Matter" and "The Law of Definite Proportions"
This scientist discovered the proton and the nucleus, leading him to also discover that most of the atom is actually made up of empty space where the electrons reside.
Who discovered the electron?
This scientist discovered that there was another particle inside the nucleus and that it did not have a charge. He called this subatomic particle the Neutron
Who was the first scientist who said that ATOMS could be broken down into/that it contained smaller parts when he discovered the first subatomic particle.
Which scientist came up with this model that said electrons floated freely in a positively charged space? It is often referred to as the Plum Pudding Model

Whose model of an atom said that protons exist inside a space called the nucleus while electrons float randomly around the nucleus in a free space?
HINT: It was called the Nuclear model due to the discovery of the nucleus
