1. Naming Covalent Compounds Covalent Bond – bonds formed from atoms sharing pairs of electrons NO charged particles / ions involved Sharing electrons between atoms  Each atom “donates” one electron to the shared pair

2. Naming Covalent Compounds Binary Covalent Compounds  2 element compounds  For two-element covalent compounds numerical prefixes are used to tell how many atoms of each element are contained in the compound.

3. Naming Covalent Compounds 1. Write both element names 2. Add prefixes for both elements 3. For the second element only, drop the ending and add “-ide” 4. The first element never uses “mono-”

4. ****NO IONS and NO CHARGES**** Dodeca- = 12 Dodeca- = 12
