The nucleus of an atom is made of

• electrons and protons
• electrons and neutrons
• protons and neutrons
• empty space

Outside the nucleus of an atom are these

• protons
• neutrons
• quarks
• electrons

Most of the volume an atom is made of this

• the nucleus
• the protons
• the neutrons
• empty space

Protons have a mass of

• 1 gram

• 1 mg

• 1 amu

• 1.67 g

Each element is determined by

• the number of protons

• the number of nucleons

• the total of the subatomic particles

• the amount of mass in the nucleus

The mass of neutron

• 1 x 10 to the -24 amu
• 1 amu
• -24 g
• -24 ng

The mass of this particle is so small that it is not counted.
