Formation of Ions

Question 1

When are Ions made?

Answer 1

Ions are made when Electrons are transferred

Question 2

What are Ions?

Answer 2

Ions are charged particles - they can be single atoms (e.g. Cl-) or groups of atoms (e.g. NO3-).

When atoms lose or gain electrons to form ions, all they’re trying to do is get a full outer shell (stable electronic structure)

Question 3

Which Groups (on the periodic table) are most likely to form Ions?

Answer 3

Groups 1 & 2 and 6 & 7 are the most likely to form Ions.

Because they only have to gain or lose maximum 2 electrons to make a stable full outer shell, and form an Ion.
