An atom is

• An Electron particle
• A Proton particle
• A basic particle of matter
• A molecule

Which of these is in the nucleus of an atom?

• Electron and Proton
• Proton and Neutron
• Neutron and Electron
• Only Protons

Which of these is spinning around the outside of the nucleus?

• Proton
• Neutron
• Atom
• Electron

The atomic number of an element means the number of

• Protons
• Neutrons
• Electrons
• Atoms

Which of these make the atomic mass of the atom?

• Only Neutrons
• Protons and Electrons
• Neutrons and Protons
• Only Protons

Which of these have a plus or minus electric charge?

• Only Electrons
• Protons and Electrons
• Neutrons and Protons
• Only Protons

This particle is the only one with NO electric charge:

• Electron
• Atom
• Neutron
• Proton

You can determine how many neutrons an element has by doing this:

• Add together the atomic number and the mass
• Subtract the number of protons from the number of electrons
• Add the mass and the atomic number
• Subtract the atomic number from the atomic mass

Which of these is NOT an element?

• Carbon
• Gold
• Hydrogen
• Particle

The Periodic Table of the Elements shows

• All the elements in the universe.
• Most of the elements in the universe.
