Abiochemist who is studying the properties of certain sulfur (s)-containing compounds in the body, wonders whether trace amounts of another nonmetallic element might have similar behavior. to which element should she turn her attention? ]

Explanation:

It is known that sulfur is a group 16 element. And, elements which are present in the same tend to show similar chemical properties because they contain same number of valence electrons.

As a result, they tend to show similar chemical reactivity and other similar chemical properties.

All the elements of group 16 are O, S, Se, Te, and Po.

Generally oxygen exists as a diatomic molecule or non-metal. But S and Se exists as polyatomic non-metals.

Thus, we can conclude that she should turn her attention to selenium (Se) element.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
