  • They are all nonreactive as they have a full outer shell.
  • They all react with water and oxygen.

7. What do periodic table columns have in common?

  • The elements have the same number of electrons in the outer shell, so have similar chemical properties.
  • The number of electrons in the inner shell is the same, meaning that they have same chemical properties.
  • The chemical properties are completely different but the number of electrons in the outer shell is exactly the same.

8. In an atom, what do the number of protons equal?

  • The number of electrons.
  • Nothing, they don't relate to anything.
  • The number of neutrons.

9. Why do atoms bond?

  • To have an outer shell full of electrons so the atom is stable.
  • To create a new atom to react.
  • So they can get rid of electrons.

10. What is the MASS NUMBER?

  • The number of protons+neutrons.
  • The number of electrons.
  • The amount of atoms.

11. What charge does an atom have?

  • Neutral.
  • Positive.
  • Negative.

12. Which best describes a compound?

  • Part of an element.
  • More than one atom bonded together.
  • A few elements combined.

13. What is the atomic number?

  • The number of protons.
  • The number of atoms.
  • The number of compounds in an atom.

14. Which best describes an element?
