Matter, Atoms, & Periodic Table Assessment

What are the subatomic particles which make up the atom?

• protons

• neutrons

• electrons

• all the other answers are correct

Which subatomic particles are found in the center (aka nucleus) of the atom?

• protons

• neutrons

• electrons

• protons and neutrons

Which subatomic particles are found in orbiting pathways outside the atom’s center (aka nucleus)?

• protons

• neutrons

• electrons

Which subatomic particle count(s) determines which element box on the Periodic Table we are talking about?

• protons

• neutrons

• electrons

Which subatomic particles have no charge? They are “neutral.”

• protons

• neutrons

• electrons

Which subatomic particles have a (-) charge?

• protons

• neutrons

• electrons

Which subatomic particles must be added together to give you an overall “net charge?”

• protons

• neutrons

• electrons

• protons and neutrons

• protons and electrons

Which subatomic particles contribute to the mass of the atom significantly?

• protons

• neutrons

• electrons

• protons and neutrons

• protons and electrons

If you change the number of protons in the center of an atom, will that change its element identity? That is, will we be talking about a different element box on the Periodic Table?

• yes

• no

If the number of protons equals the number of electrons, what do you call the resulting atom?

• an ion

• a neutral atom

• a stable atom

• a substance
