Nomenclature & Chemical Notation Flashcards
What breaks up covalent bonds?
Lightning
What breaks up ionic bonds?
Water
Describe binary compounds
Contain 2 ELEMENTS.
Must have 0 charge
Can have many atoms, but only 2 elements
Ex: N2O4
How to name ionic compounds
Made of metal and non metal
Name the metal & the non metal. Add the suffix ide.
NO PREFIXES
Name:
- NaCl
- Li2S
- K2S
- Sodium Chloride
- Lithium Sulphide
- Potassium Sulphide
How are ionic bonds named with transition metals?
Roman numerals are used to illustrate the # of bonds or the # of electrons that will be transferred
THE CHARGE OF ONE OF THE TM ATOMS
Name:
- Au2S3
- CuF2
- TiCl4
- PbBr2
- Fe2S3
- gold (III) sulphide
- copper (II) fluoride
- titanium (IV) chloride
- lead (II) bromide
- iron (III) sulphide
Name:
- Na2SO4
- Fe(NO3)3
- NH4Cl
- Cu(NO3)2
- sodium sulphate
- iron (II) nitrate
- ammonium chloride
- copper (II) nitrate
Describe naming covalent bonds
- made up of 2 non metals
Prefix(di, tri, tetra, penta)+name of first non metal + prefix(MONO, di, tri…)+name of second nonmetal + “ide”
ide is ate when polyatomic
Name prefixes from 1-6 for covalent bonds
mono di tri tetra penta hexa
Describe writing molecular formulas
- Write the symbols of the two elements, placing the metal first
- Write the number of bonds that each element can form on top of each symbol
- Cross them over - they become subscripts
- Divide subscripts to lowest common multiple (Simplify
- Drop any 1s

- MnS2
- K3N
- Al2S3
- Cu3N2
- FeBr3
Find the formula for:
- aluminium ion with sulpahte ion
