The number of protons and electrons is equal on the periodic table, because the periodic table is assumed to be neutral
(which means each atoms has an equal amount of negatively charged electrons & positively charged protons)

True

False

The atomic mass represents ONLY the neutron count for the atom.

Atomic Mass = Neutron #

True

False

We NOW (currently) know that electrons move slowly on orbits around the nucleus.

True

False

The ___________ is the name of the model that mirrors our current understanding 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 behavior and workings of atoms, 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 the neutron and that it had the greatest mass

Who was the first scientist that said that ATOMS could be broken down into smaller parts when he discovered the first subatomic particle.
