Transcript of Chemistry Review. The atom Protons, electrons,neutrons.
Chemistry Review
The atom
• Protons, electrons ,neutrons
Periodic table
Ionic bond metal - nonmetal
Covalent bondSharing of electrons
Nomenclature Naming
• Simple binary
• First element unchanged
• Second element used as prefix with –ide
• Example
• Li2O
• Fist element lithium second element oxygen
• Name lithium oxide
MultivalanceRoman numeral needed• Identify the first element( check if it’s multi
valence):identify the second element
• If the first element is multivalance you need to check which oxidation state will balance the charge on the second element and include it as a roman numeral
• CuCl2 Copper is multivalance
• Cl has an oxidation state of-1 and there is two of them to balance this the one Cu must have an oxidation state of +2
• Answer : copper(II) chloride
polyatomic
Formulas - given names
• Example
• Barium chloride
• Look for barium and chlorine on periodic table –determine their oxidation state
• Ba second column +2
• Cl Seventh column -1 Ba+2Cl-1
• Criss-cross Answer: BaCl2
