This is called an electron.

Electrons
The electron cloud.
It must take electrons from either another atom or be ionized. If it takes electrons from another atom then it has more electrons than protons, which gives it a negative charge.
A positively charged part of an atom is called a proton. It is located in the nucleus of the atom along with neutrons and is balanced by negatively charged electrons orbiting the nucleus.
Neutrons
Not quite. You can have an atom of an element, for example an atom of Hydrogen, but not a Hydrogen of an atom. The parts of an atom are protons (positively charged), neutrons (no charge), and electrons (negatively charged).

Electrons are negatively charged sub atomic particles.
