Naming and Formulas for Covalent Compounds Unit 6 – Part II

3/21/2016Free template from Naming Covalent Compounds Systematic (Prefix Method) 1. First element (least electronegative) named first using full element name 2. Second element name as if it were an anion (-ide) 3. Prefixes used to denote # of atoms present 4. mono is NOT used for the first element

3/21/2016Free template from Prefixes 1 – mono7 - hepta 2 – di8 - octa 3 – tri9 - nona 4 – tetra10 - deca 5 – penta12 - dodeca 6 - hexa

3/21/2016Free template from Naming Covalent Compounds Examples N 2 O –Dinitrogen monoxide NO –Nitrogen monoxide NO 2 –Nitrogen dioxide

3/21/2016Free template from Naming Covalent Compounds N 2 O 3 –Dinitrogen trioxide N 2 O 5 –Dinitrogen pentoxide

3/21/2016Free template from Writing Formulas for Covalent Compounds Just the opposite of naming – look at the name and reverse it back to the formula.
