What to Focus On

  • Atomos means indivisible.
  • Atom is the smallest particle of an element that shows all its properties.
  • Atoms of the same element are alike.
  • Atoms contain electrons, protons, and neutrons.
  • Electrons are negative and have very small mass.
  • Protons are positive and are in the nucleus.
  • Molecules have independent existence.
  • A molecule may contain atoms of one element or different elements.
  • Atoms join in fixed whole number ratios in compounds.

Common Mistakes to Avoid

An atom and a molecule mean the same thing.

All atoms of an element can exist alone in nature in the same way.

Atomicity means the number of atoms in any molecule, even if they are different elements.
