Chemistry Unit 4 🥼- Bonding and Nomenclature

formed when 2 nonmetals SHARE electron formulas DON”T reduce.

Covalent Bonds (Definition)

Covalent bonds are 2 _____ sharing an electron

nonmetals

EN Diff for Polar Covalent Bonds

0.5 - 1.69

the TRANSFER of electrons from metals (cations) to nonmetals (anions)

Ionic Bonds (Definition)

Ionic bonds connect _______

Metals and Nonmetals

EN Diff for Non polar Covalent Bonds

0 - 0.49

Whose Characteristics are these: Mostly Solid, High Melting and Boiling Point because bonds are so strong, Dissociate in water, Conduct electricity.

Ionic Bonds

Whose Characteristics are these: Unequal sharing (Atom with higher EN pulls other atom towards itself), Solid Liquid and Gas, Dissolves in Water, Does NOT conduct electricity.

POLAR Covalent Bonds

Whose Characteristics are these: Equal Sharing, Solid Liquid and Gas, Low Melting and Boiling Point, Does NOT dissolve in water, Does NOT conduct electricity.
