22.2 Notes – Types of Bonds Part A

Objective Describe ionic bonds. Identify the particles produced by ionic bonding

Ionic Bonds & Ionic Bonding Video Watch the Tyler DeWitt Video and complete the viewing guide, you will add it to your notes on this chapter Youtube video

Ion An atom that has lost or gained electrons Becomes charged since # of protons no longer equals # of electrons Atoms lose or gain to meet a standard—a stable energy level

Ionic Bonds Oppositely charged particles are held together by electric forces in a compound Lots of energy released Positive charge is balanced by negative charge

Ionic Bonds Zero net charge Metal + nonmetal Neutral compound Metal + nonmetal Elements on opposite sides of periodic table YouTube Video - NaCl

Metal Ion Loses 1+ electron from outer energy level Becomes a positive ion CATION Fewer electrons than protons

Non-metal Ion Gains 1+ electron in its outer energy level Becomes a negative ion ANION More electrons than protons
