Q: What is the term for  a particle outside the nucleus of an atom that has a negative electric charge?


Read this paragraph and choose the correct option from the provided answers:

An electron is a particle outside the nucleus of an atom that has a negative electric charge. The charge of an electron is opposite but equal to the charge of a proton. Atoms have the same number of electrons as protons. As a result, the negative and positive charges "cancel out. " This makes atoms electrically neutral. For example, a carbon atom has six electrons that "cancel out" its six protons.

 Choices:

- proton

- ion

- neutron

- electron


A:
electron
