concept 4 covalent bonds

explain the connection between electronegativity and the formation of covalent bonds.

Covalent bonds are formed when nonmetallic elements share electrons

vocab

Covalent compound = a compound formed when two or more atoms share e-. covalent bond = formed when nonmetallic elements share e-. molecule= a neutral group of atoms held together by covalent bonds diatomic elements= when 2 atoms of the same elements exist naturally as a molecule.

Differentiate between polar covalent and nonpolar covalent bonds. Give an example of each.

In polar covalent, the electron is unequally shared. In nonpolar covalent bonds, electrons are shared equally.

Write chemical formulas for the following compounds: a. Boron tribromide b. carbon tetrafluoride c. Diphosphorus trisulfide d. nitrogen trihydride

a. BB3 b. CF3 c. P2S3 d. NH3

Name the following compounds: a. N2O3 b. SO2 c. N2S d. B2H4

a. dinitrogen trioxide b. sulfur dioxide c. dinitrogen sulfide d. diboron tetrahydroide

Explain how the VSEPR theory impacts how you draw Lewis structures for molecular compounds.

shows how to be far apart of electron pairs from one another.

Differentiate between single,double, and triple bonds.

single 2 electrons are shared. double 4 electrons are shared. triple 6 electrons are shared.
