An atom is the smallest particle of a substance that can take part in a chemical reaction. It is composed of subatomic particles.

The statements that best describe an atom are;

  • contains subatomic particles named the proton, neutron, and electron
  • has no net charge and has a cloud surrounding a dense inner core
  • is the smallest particle of an element that retains its identity in a chemical reaction

Atoms of elements are the smallest particle of the element. According to the law of conservation of mass, atoms of elements retain their identity in a chemical reaction.

An atom is composed of a massive inner core having neutrons and protons and then a cloud of charge hovering over this dense inner core.

The atom has no net charge because the number of protons and electrons are exactly equal.
