Remember…Remember…Atoms combine by gaining, losing Atoms combine by gaining, losing or sharing electrons in order to or sharing electrons in order to become chemically stable.become chemically stable.

Atoms become chemically stable Atoms become chemically stable by having a full outer shell with 8 by having a full outer shell with 8 valence electrons. (Octet Rule)valence electrons. (Octet Rule)

Types of BondingTypes of Bonding

Today we will focus on the Today we will focus on the 2 main types of bonding:2 main types of bonding:

Ionic Bonding & Covalent Ionic Bonding & Covalent BondingBonding

Ionic BondingIonic BondingIonic bonds form when a metal Ionic bonds form when a metal and a nonmetal transfer and a nonmetal transfer electrons.electrons.

Remember the octet rule-Remember the octet rule-elements are the most stable elements are the most stable when they have eight valence when they have eight valence electrons in their outer shell.electrons in their outer shell.

Ionic BondingIonic BondingIons are formed by the Ions are formed by the giving and taking of giving and taking of electrons. electrons.

The bond that forms The bond that forms between ions is an between ions is an ionic ionic bondbond..

Ionic BondingIonic BondingElements with only a Elements with only a few valence electrons few valence electrons will give electrons will give electrons away to elements that away to elements that only need a few to only need a few to complete their octet.complete their octet.

Ionic BondingIonic Bonding What is the charge of an What is the charge of an element that loses electrons?element that loses electrons?POSITIVEPOSITIVE

What is the charge of an What is the charge of an element that gains electrons?element that gains electrons?NEGATIVENEGATIVE

Ionic BondingIonic BondingWe can use electron dot We can use electron dot diagrams to illustrate the diagrams to illustrate the gaining and losing of gaining and losing of electrons in an ionic bond.electrons in an ionic bond.
