1. Compounds

2. Ionic compounds Compound between Non-metal and metal Ionic bond
Large difference in electronegativity
(how much the atom wants an electron)
Found in solid form at SATP
Conducts electricity in aqueous solution
When combined the cation is used followed by the anion, the cation is used in full and the anion has a –ide suffix: oxide, fluoride

3. Cont’d Multi valent metals Different possibilities for ion charge
Iron, Copper
Check period table for common ion charge

4. Molecular Elements Elements ending in –gen are diatomic.
Pg. 33 – should know this table
Elements ending in –gen are diatomic.

5. Molecular Compounds Compounds of non-metals Covalent bond
Small difference in electronegativity
Found in all three states of matter at SATP
Does not conduce electricity

6. Acid and Base Compounds
Identified by the H- prefix and occasionally the –COOH on the end of the compound
Found in all three states of matter at SATP
Conduce electricity in aqueous solution
Made of non-metals – assumed to be ionic
Acid pH below 7 – aqueous hydrogen
Base pH above 7 – aqueous hydroxides

7. Acid naming Classical naming (for information)
hydrogen _____ide -> hydro_____ic acid
hydrogen _____ate -> ______ic acid
hydrogen _____ite -> ________ous acid
hydrogen hypo_____-> hypo_____ous
IPUAC naming (good to know basic)
hydrogen ______

8. States of matter in a compound
The state of matter is also given in the compound
i.e. H20(s), H20(l), H20(g)
NaCl(s) or NaCl(aq)
Aqueous solution – the solvent is water (dissolved in water) - homogenous mixture in one phase
Solvent – a substance that dissolves a solute
Solute – substance that is dissolved into a solution
