Compounds-Stable (do not easily change)

-Most atoms are bonded into compounds

-Separated with chemical reactions

-Usually need high heat or electricity

Ionic CompoundsMetals lose valence electrons

Non-metals gain valence electrons

Page 5: Warm-up: Ionic Bonds Ionic Compounds – names & formulas ◦ Binary ◦ With Roman numerals ◦ With 3 or more elements Covalent Compounds (molecules)

Ionic bonding occurs when a metal loses 1+ electrons to a non-metal in an effort to attain a stable octet of valence electrons.

Use Electron Dot Diagrams (Lewis diagrams) to show the ionic bonds for one formula unit.

Na Cl = Na⁺¹Cl⁻¹

Ionic Bonding: Transfer of valence electrons

Ionic Compounds - Opposites Attract

Separate cations and anions to bond◦ Use only the single element ions (not the polyatomic

ions) Write the symbol and the charge

Write the new compound formed by combining the ions. Write the formula showing that the charges (oxidation numbers) add up to 0 (cancel out)

Name the compound. Write at least 15 compounds.

◦ Ten should include subscripts.

Page 16: Warm-up: Ionic Bonds Ionic Compounds – names & formulas ◦ Binary ◦ With Roman numerals ◦ With 3 or more elements Covalent Compounds (molecules)

a. The formula for ionic compounds are determined by the charges (oxidation numbers). The overall charge of the compound must equal 0.

b. The charges are determine by the number of valence electrons that the element loses or gains to reach 8 valence electrons. This is the octet rule that makes the compound stable (does not easily react.)
