ATOMIC STRUCTURE

  In the centre of an atom there is a small nucleus that contains 2 types of particles called protons and neutrons. There is a third type of particle which orbits around the nucleus called electrons. An atom has the same number of electrons around it as it has protons and neutrons' inside it.

Protons = postive charge (+1)

Neutrons= neutral (so the nucleus has an overall posyive charge.)

Electrons= negatively charged (-1)

An atom contains equal numbers of protons and electrons causing each other to cancel out and cause no overall charge for an atom.

Question... If an oxygen atom has 8 protons, how many electrons does it have?

Answer... all atoms have the same number of protons and…
