Question

What is the negatively charged atomic particle of an atom called?

Answer 1

Electrons

Explanation:

The negatively-charged particles of an atom is called the electron. This is a very important particle in chemistry and physics, especially in the quantum world. It basically "governs" the quantum realm.

It has a mass of approximately `9.11*10^-31 \ "kg"`, and has a charge of `-1`. It can be found on the electron shells of an atom, which are usually circular orbits around an atom's nucleus.

To predict where an electron can be found in an atom, we need to use atomic orbitals and quantum numbers, but I won't be discussing that here.

Here is a picture of a carbon atom with electrons:
