Question

Is atom indivisible.

Answer 1

No. It is made up of neutrons,protrons and eletrons.
the word atom is greek for 'indivisible' it was named so beacuse the scientists at that time thought atom was indivisible.
Evenhe individual neutron, protons and electrons themselves can also be divided into quarks or god particles (higgs boson) and other unusual particles that are currently being investigated by scientists.
so no atom is not indivisible. it can be divide to smaller units that make up atom.
