Ch 5 Covalent Bonding Remember… Covalent molecules are made from 2 or more nonmetals and the electrons are “shared.”

Diatomic Molecules Gases made of two atoms of the same element. Naming – just use the element name Hydrogen Fluorine

Prefixes Used in Covalent Molecules Don’t use for first element

Example

Practice HI hydrogen iodide NF3 nitrogen trifluoride SO2 sulfur dioxide N2Cl4 dinitrogen tetrachloride TOXIC! NO2 nitrogen dioxide N2O dinitrogen monoxide Laughing Gas

More Practice P4S3 I2O5 CS2 B2Cl4 Tetraphosphorus trisulfide Diiodine pentoxide Carbon disulfide Diboron tetrachloride

Naming Covalent Molecules - just follow the name prefixes tell what the subscripts should be of each element Examples: Phosphorus triiodide Chlorine tetrabromide Tetraphosphorus hexoxide PI3 ClBr4 P4O6
