Question

Atom is made up of what ???
And the particles that join to make a atom , From what that particles are made up of ???​

Answer 1

Answer:

They're typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the centre of the system. The electrons orbit this nucleus, like planets. If atoms are impossibly small, these subatomic particles are even more so.

Atoms are made up of particles called protons, neutrons, and electrons, which are responsible for the mass and charge of atoms.

Answer 2

An atom is made up of electrons (negatively charged particles), protons (positively charged particles) and neutrons (no charge). It is not know yet what are these made up of but according to one theory these are made up of minute particles called quarks. It's just theoretical.
