Element X is a solid that is brittle, lacks luster, and has six valence electrons. In which group on the Periodic Table would element X be found?(1) 1 (3) 15
(2) 2 (4) 16
Group 16 elements of the periodic table is called the oxygen family. They are also called Chalcogens since they are found as compounds or ores in the earth's crust.
These elements like oxygen, they have six electrons in the outermost energy level, thus they have a valency of two as they require 2 electrons to attain a stable configuration. Examples of elements in this groups includes, oxygen, polonium, sulfur, and selenium.
Therefore, due to the fact that element X has six outermost electrons then it belongs to group 16.
