Answer 1

Fundamental particles

Explanation:

Matter is anything that occupies space. It can be a solid, liquid or gas. Matter is made up of atom. Atom is the smallest piece of a particle. It is the basic part of any element.

An atom contains neutrons, protons and electrons. Electrons are positively charged particles and protons are positively charged particles. Number of electrons is always equal to the number of protons in an atom. The number of protons in the nucleus of the atom is the atomic number of the element. The sum of the number of protons and neutrons in the nucleus gives the mass number of the element.
