No charge
What is the charge of an electron?
Negative charge
What is the location of a proton?

Nucleus
What is the location of an electron?
Orbiting the nucleus
Why is an atom neutral (uncharged) even though its subatomic particles are charged?
In uncharged, neutral atoms, the number of electrons orbiting the nucleus is equal to the number of protons inside the nucleus. The negative and positive charges cancel out, leading to an atom with no charge.
