Chemistry Concepts - 6 Chemical Bonding When an atom lacks a stable number of electrons In its outer energy level, it will share or transfer electrons to or from other atoms in very precise ways to achieve a stable number of electrons (again, generally 8) in its outer shell. This is the subject of chemical bonding. Note that a chemical bond is an energy relationship, involving electrons, and the energy that each electron has. The energy all living organisms need to sustain life comes from making and breaking chemical bonds. It’s vital that we understand how this works!

Unformatted text preview: Types of Bonds There are two types of common or strong bonds that occur between atoms: Ionic bonds One or more electrons are transferred from one atom to a second atom. When an atom gains or loses one or more electrons, it becomes a charged atom, or an ion, because its number of electrons relative to the number of protons has changed. Covalent bonds Electron(s) of one atom are shared with electron(s) of a second atom. Atoms that form covalent bonds do not carry a charge. Let's looks a little at these two types of bonds....
