5. An atom has the same number of protons and electrons.
If an atom has gained or lost an electron or some electrons THEN IT IS NO LONGER CALLED AN ATOM.
It is called an ION.

10. Helium, Neon and Arg0n do not lose or gain electrons.
Write a sentence explaining why.

11. New Buzzwords (Jargon)
In the periodic table, we can look at elements that are in the same vertical column, e.g. Be, Mg, Ca. These are called a GROUP.
In the periodic table, we can look at elements that are in the same horizontal row, e.g. Na, Mg, Al, Si, P, S, Cl, Ar, Ca. These are called a PERIOD.
Elements in the same PERIOD have the same number of layers (shells) of electrons but different numbers in the outside layer.
Elements in the same GROUP have the same number of electrons in the outside layer but different number of layers (shells). Elements in the same group tend to react similarly because the reactions are caused by the electrons in the outside layer.

12. Tough Group Task
Write a paragraph discussing the similarities and differences between atoms of Hydrogen, Lithium, Sodium and Potassium in terms of their:
Position on the periodic table
Their state at room temperature and atmospheric pressure
Electron arrangements
Ions that they form.
