What to Focus On

  • Paramanus means ultimate particle.
  • Atom means indivisible.
  • Dalton gave the first scientific theory of matter.

  • Electrons are negatively charged particles.
  • Protons are positively charged particles.
  • Neutrons are neutral particles.

  • Electron: negative charge, very small mass, outside nucleus.
  • Proton: positive charge, nucleus, mass about 1 amu.
  • Neutron: no charge, nucleus, mass about 1 amu.

Common Mistakes to Avoid

Atomic number and mass number mean the same thing.

Hydrogen always has one neutron because all atoms have protons, neutrons, and electrons.

Electrons and protons are distributed randomly in the atom.
