Atom is made up of what ??​

Answer 1

Answer:

An atom is the smallest part into which an element can be divided.

Atoms are actually made up of different types of stable and unstable particles. Prominent of them are Electrons, Protons and Neutrons

Answer 2

An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across.

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.
