Who was the Greek philosopher who first suggested that matter was composed of indivisible particles which he referred to as atomos?

• Dalton

• Democritus

• Einstein

• Plato

J.J. Thomson discovered the presence of the first subatomic particle, which was called the:

• atom

• proton

• electron

• nucleus

Through the Gold Foil Experiment, Rutherford showed the existence of what important atomic structure?

• the electron cloud

• the nucleus

• the alpha particle

• the neutron

One of the major differences between the 1st Atomic Theory presented in the 1800's and the Modern Model of the atom of today is:

• That atoms of all elements are the same.

• That atoms can be decomposed (broken down) into other atoms.

• That atoms do not contain a nucleus.

• The atom can be divided into subatomic particles.

Which two subatomic particles can be found in the nucleus of an atom?

• ribosomes and endoplasmic reticulum

• neutrons and protons

• electrons and protons

• protons and alpha particles

Which one of these statements is true regarding the first Atomic Theory that was proposed in 1803?

• The atom contains a dense core called the nucleus.

• Electrons orbit the nucleus in energy levels.

• That matter is conserved in a chemical reaction.

• Atoms are indivisible and indestructible.
