Atoms

The smallest particle into which an element can be divided and still be the same element is a(n)

• proton

• neutron

• electron

• atom

Which subatomic particle has a positive charge?

• proton

• nuetron

• electron

• atom

Which subatomic particle has a negative charge?

• proton

• neutron

• electron

• atom

Which subatomic particle has a neutral (0) charge?

• proton

• nuetron

• electron

• atom

Why is the overall charge of an atom neutral (0)?

• They have the same number of protons and neutrons.

• They have the same number of protons and electrons.

• They have the same number of electrons and neutrons.

Which TWO of the following subatomic particles are inside the nucleus?

• protons

• electrons

• neutrons

• There are no subatomic particles in the nucleus of an atom.

The number of which subatomic particle determines the element of an atom (if it's carbon, oxygen, nitrogen, etc.)?

• proton

• neutron

• electron

• Subatomic particles do no determine the element of an atom.
