1How do you name ionic compounds
Positive ion first followed by the negative ion
2Which ion is usually the positive ion and which is the negative ion respectively?
Metal and then non-metal
3What does the name of the 2nd ion, say oxygen change to when in an ionic compound?
Oxide
4What are the prefixes for the number of atoms in a molecule for 1, 2, 3, 4, 5 & 6
mono, di, tri, tetra, penta & hexa
5If the ionic compound contains a metal, do you have to name it with numbers?
No
6What is the valency of an atom
It is the number of electrons taken in or given away in bonding or involved in bonding
7What is the valency and charge of silver?
1 & +1
8What is the valency and charge of zinc?
2 & +2
9What is the formula for hydroxide
OH-
10What is the formula for nitrate
NO3-
11What is the formula for carbonate
CO3 2-
12What is the formula for sulfate
SO4 2-
13What is the formula for ammonium
NH4+
14What is a polyatomic ion
It is a group of different atoms covalently bonded as one unit but with charge distributed over the unit. They react as a single group.
15What extra step do you have to do when writing chemical formula for ionic compounds involving polytomic ions
Add brackets to them if there is a subscript after it
16What do the names of polyatomic ions end with
-ite or -ate
17What is the formula for hydrochloric acid
HCl
18What is the formula for sulfuric acid
H2SO4
19What is the formula for nitric acid?
HNO3
20What is the formula for ammonia
NH3
21What is the formula for methane
CH4
22What does the state symbol of aquaeous mean?
A substance that is dissolved in water to form a solution
23What are SPAN salts and are they soluble in water
Sodium, potassium, ammonium and nitrates. Yes
24Which chlorides are insoluble in water
lead (||) & silver
25Which sulfates are insoluble in water
calcium, lead (|||) & barium
26Which carbonates are soluble in water
sodium, potassium & ammonium
27In chemical equations, which elements do you balance last?
Oxygen and Hydrogen and between those 2, balance the one with lowest number first
28What are spectator ions?
Substances present in a chemical reaction but do not take part in it and therefor remain unchanged
29What are the steps to make a balanced chemical equation into an ionic one
1. Rewrite the substances as their constituent ions 2. Cancel out the spectator ions on both sides
