Thak you so much Ian!
Don't worry too much Micheal . An atom is composed of electrons which are negatively charged, protons(positively charged), and neutrons(neutral). You should also know that an atom is the smallest unit of matter.
You just asked in time for the quiz. Well, a ionic bond is a chemical compound formed when one one or more electrons are transferred from one atom to another and a covalent bond is between atoms and electrons are shared.
