  • What is the charge of protons in an atom?
    Protons are positively charged
  • What initially shaped Earth’s early atmosphere?
    Volcanic activity and outgassing shaped Earth's early atmosphere.
  • Which parts of the atom move around the nucleus?
    Electrons move around the nucleus.
  • What is the atomic number for an element with three protons?
