2. What makes up the nucleus of an atom?

  • Protons and neutrons.
  • Neutrons and electrons.
  • Electrons and Protons.

3. Why is an atom neutral?

  • Because there is an equal number of protons and electrons which balances the number of positive and negative charges.
  • Because there are more neutrons than protons and electrons so there is a stronger neutral charges.
  • Because there are only neutrons in the nucleus which is the heaviest part meaning the overall charge is neutral.

4. Why are elements in the same group together?

  • Because they have the same relative mass.
  • Because they have the same number of electrons on their outer shell.
  • Because their electrons occupy the same number of shells.

5. How are the elements arranged in the periodic table?

  • By increasing number of electrons.
  • By increasing atomic number.
  • By decreasing relative charge.
