Chemical BondingChemical Bonding
atoms give up or gain electrons and are attracted
Na loses an e–
Na Na1+ + e–
(Metal)
Cl gains an e–
Cl + e– Cl1–
(Non-Metal)
ionic compounds = salts Na1+ + Cl1– NaCl
K1+ + NO31– KNO3
where NO31– is a polyatomic ion: a charged group of atoms
that stay together

Properties of Ionic CompoundsProperties of Ionic Compounds
VERY HARD each ion is bonded to several oppositely-charged ions
HIGH MELTING POINTS many bonds must be broken
BRITTLE with sufficient force, like atoms are brought next to each other and repel
