1. Naming chemicals
Name chemical substances from their formula and write simple word equations

2. Ideas: do not copy You need to know some simple names and formulas
On the next couple of pages are some simple elements that you need to be able to name.
We then move onto how ions are formed and how they work to make up compounds.
We then move onto the more complicated ions and finally onto the formulas.

3. Common elements Si P S Cl K Ca Cu Zn Pb Silicon Phosphorus Sulfur
Chlorine
Potassium
Calcium
Copper
Zinc
lead H Li C N O F Na Mg Al
Hydrogen
Lithium
Carbon
Nitrogen
Oxygen
Fluorine
Sodium
Magnesium
Aluminium

4. Common ions Chloride Oxide Hydroxide Carbonate Sulfate Nitrate
Hydrogen carbonate
Cl -
O 2-
OH -
CO32-
SO42-
NO3-
HCO3-

5. How do ions form?
Ions are formed when an element either gains electrons (negative ion, anion) or when it loses electrons (positive ion, cation)
Elements can only lose or gain electrons. The number of protons and neutrons remains the same.
Remember: in an element (atom) the number of protons equals the number of electrons. In an ion, the number of protons stays the same and electrons can change.

6. Which atoms lose electrons?
Metals lose electrons to become positively charged.
Move onto the board to show them more examples.

7. Which atoms gain electrons?
Non-metals gain electrons to become negatively charged.
