The name of the group is the oxygen family. The valence number for elements in that group are -2. (gain or share two electrons) Oxygen, sulfur and selenium are nonmetals. Tellurium and Polonium are metalloids.

The nonmetallic properties of elements in Group 16 (also known as the oxygen group) increase as you move down the group. This trend is due to the increase in the number of valence electrons and the atomic size, leading to stronger electronegativity and electron affinity. Elements like oxygen and sulfur exhibit typical nonmetallic properties, such as gaining electrons in chemical reactions.

Elements become more nonmetallic as you go from left to right on the Periodic Table, and also as you go from the bottom to the top. So the most nonmetallic element is fluorine (which is to say, it has the highest electronegativity) and it is in the upper right hand corner - except for the noble gases which are inert, and are even farther to the right.
