Elements are those substances that contains atoms that are indivisible by any chemical means.
The properties of these elements varies in a particular manner, therefore they are distributed into groups.
Based on the descriptions from the question, the groups are:
- Group 7: Chlorine is a highly reactive gas found in group 7 because it contains seven valence electrons in its outermost shell.
- Group 1 : Potassium is an extremely reactive metal found in group 1 because it contains only one valence electron in its outermost shell.
- Group 4: Silicon is a metalloid that belongs to group 4 because it contains four valence electrons in its outermost shell.
- Group 2: Calcium belongs to group 2 because it contains two valence electrons in its outermost shell.
- Group 0: Neon is an inert gas found in group 0 because its outermost shell is completely filled up.
- Group 3: Aluminum is the most abundant metal found in he earth crust which belongs to group 3. This is because it contains only 3 valence electrons in its outermost shell.
