What are bonds?

What are bonds?. Elements are the simplest substances that exist on Earth. Each element is made up of just one type of atom, usually joined to other atoms of the same element by bonds. This forms molecules such as chlorine (Cl 2 ).

How do atoms form ions?

How do atoms form ions?. An ion is an atom or group of atoms that has an electrical charge, either positive or negative. Atoms have an equal number of protons and electrons, and so do not have an overall charge.
