Orbiting around the nucleus are electrons (tiny particles each with a single negative electric charge).The atoms of each element may vary slightly in the numbers of neutrons within their nuclei.So, for example, every carbon atom contains six protons and six electrons, but the number of neutrons in each nucleus can be six, seven, or even eight.
