ATOM or ion?
Atom is the smallest and most indivisible unit of matter If our atom gains or loses electrons it
becomes an ion
H+ -
Lost e- Gained e-
NEUTRAL
Negative ionPositive ion
“Cation”“Anion”
Naming Ionic Compounds
Rules: The metal goes first Second is the nonmetal + ide
Example 1: Lithium and Bromine LiBr
Example 2: Calcium Fluoride =
What does “ide” look like??
Br = Bromide I = ________________________ O = ________________________ F = _______________________ N = ________________________ P = ________________________ Cl = _______________________ S = ________________________ H = ________________________
How to find Ionic charges
FIND THE NEAREST NOBLE GAS Count FORWARD OR BACKWARD to
the noble gas Which direction is quicker to get to the
noble gas group? Whatever this # is, this is your charge
MOST OF THE TIME
Level 2: Write the Formula
Example: Sodium Chloride NaCl
Beryllium Bromide Cesium Bromide Sodium Fluoride Calcium Phosphide Lithium Chloride Magnesium Sulfide
Type (II) Transition Metals
Name the transition metal first. Use Roman Numerals to specify charge. Add “ide” to the end of non-metal.
Example 1: Copper (III) Iodide =
Example 2: AuI4 =
Level 3: Transition Metal Name Examples: Copper (III) Iodide = CuI3
Gold (VI) iodide = AuI4
Nickel (I) oxide Iron (V) fluoride Cobalt (II) oxide Tin (III) nitride Manganese (VII) oxide Niobium (V) chloride Titanium (III) phosphide Palladium (IV) sulfide
Level 4: Transition Metals (Other Direction)
EXAMPLES!!
Cr2O3 = Chromium (III) Oxide CuF2 = Copper (II) Fluoride
CuF PbCl4 PbI2
CrO3 NiO AuBr
Polyatomic IonsHere are some common ones:
Waste product of animals
Chemical warfare
Mixed with carbonate and water get you the “fizz” in soda!
Drinking water, soaps, detergents, and drain cleaner .Bleaching, disinfection and water treatment agents.Salts produced by bacteria that are damaging to humans and ecosystems.Used to “cure” meats.
Structural material in bones and teeth.Battery acid, soap, shampoo, toothpaste, acid rain.Wine and food preservatives.
Covalent Compounds
Are between 2 non-metals.
Rules: Name the first non-metal (most positive) Then the second non-metal + “ide” Use pre-fixes If there is no prefix use prefix of 1
Covalent Compounds
Pre-fixes 1- mono 2- di 3- tri 4- tetra 5- penta 6- hexa 7- hepta 8- octa 9- nona 10- deca
