Electrons are elementary subatomic particles with negligible mass that surround the nucleus of an atom. They are bound to the nucleus due to electromagnetic attraction, with neutral atoms having equal numbers of protons and electrons. Electrons can absorb energy and escape from the nucleus, forming i...

What is exactly equal to the total number of protons and neutrons in an atom? What chemical element has 35 protons and 36 electrons? What is the number of neutrons in Se? How can you find protons, neutrons and electrons from an atomic number? How many neutrons and protons are in helium...
For the purposes of static charges we can ignore the neutrons in an atom and concentrate only on the protons and electrons. This is because these are the only two particles in the atom that carry any charge. The charges of protons and electrons are equal and opposite to each other. ...

Passage One Atoms, the basic building blocks of matter, are made of three basic components: protons, neutrons and electrons. The protons and neutrons cluster together to form the nucleus, the central part of the atom, and the electrons orbit about the nucleus. Protons and electrons both carry...
