Answer: Oxygen is a non-metal.

Explanation:

Elements are distributed into 7 period and 18 Groups in a periodic table.

Elements are classified into three categories:

Metals: They are called as metals because they loose electrons to attain stability. These elements belong from Group 1 to group 13 of the periodic table. They are hard and are mainly solid.
Non-metals: They are called as non-metals because they gain electrons to attain stability. These elements belong from Group 15 to group 17 of the periodic table. They are soft and are mainly liquid or gases.
Metalloids: They are called as metalloids because they show properties of both metals and non-metals. These elements belong from Group 14 of the periodic table.

Oxygen belongs to Group 16 and period 2 of the periodic table.

Hence, oxygen is a non-metal.
