Atoms – 5 Points

• Everything around us is made up of tiny particles called atoms.

• An atom is so small that we cannot see it with our eyes.

• Atoms are the building blocks of matter.

• Each element (like oxygen, gold, or iron) is made of only one kind of atom.

• When atoms join together, they form molecules (like H₂O for water).

  Atomic Structure – 5 Points

• An atom has three main parts – protons, neutrons, and electrons.

• Protons and neutrons are in the center, called the nucleus.

• Electrons move around the nucleus in orbits or shells.

• Protons are positive, electrons are negative, and neutrons have no charge.

• The number of protons in an atom decides which element it is.
