Electrons and protons are particles in an atom with equal but opposite charges. Electrons have a negative charge and protons have a positive charge. What is the charge amount of an atom with 2 more electrons than protons?

Step-by-step explanation:

- Protons are positively charged particles contained in the nucleus of the atom. They have a charge of

- Electrons are negatively charged particles orbiting around the nucleus of the atom. They have a charge of  

For a neutral atom, the number of protons is equal to the number of electrons, so the total charge of a neutral atom is:

In this problem, we have an atom having an excess of 2 electrons, i.e. it has 2 more electrons than protons.

Therefore, the charge of this atom will be:
