The electrons determine the chemical වත්කම් of an element, and strongly influence an atom's [[Magnetism|magnetic]] වත්කම්.

{{මූලික|Subatomic particle}}
Though the word ''atom'' originally denoted a particle that cannot be cut into smaller particles, in modern scientific usage the atom is composed of various [[subatomic particle]]s. The constituent particles of an atom are the [[electron]], the [[proton]] and the [[neutron]], except that [[hydrogen|hydrogen-1]] has no neutrons and a positive [[hydrogen ion]] has no electrons.
