Relative Electrical Charges of Subatomic Particles

• What is the relative charge of a proton?

  +1
• What is the relative charge of a Neutron?

  0
• What is the relative charge of an electron?

  -1
• Why do atoms have no overall charge?

  In an atom, the number of electrons is equal to the number of protons in the nucleus, therefore atoms have no overall charge.
• What is an atomic number?

  The number of protons in an atom of an elemnt.
• How do atoms of different elements differ from each other?

  Atoms of different elements have different numbers of protons.
• What does the nuclear model of the atom describe?

  • Atoms consist of a dense, positively charged nucleus
  • Electrons orbit around the nucleus at a relatively large distance
