In chemistry, according to Collision theory: It states that for a chemical reaction to occur, the reacting particles must collide with one another. The rate of the reaction depends on the frequency of collisions. The theory also tells us that reacting particles often collide without reacting.
There are two kinds of ions that are cation and anion. The former type is formed by metal by the loss of electrons whereas the latter type is formed by non-metal by the gain of electrons.
Group 16 of the periodic table contains the elements whose symbols are O, S, Se, Te, and Po. The generalized configuration of electrons in the nth...
Therefore, these elements will gain two electrons and become stable by achieving an inert gas configuration that is nearest to them. Thus, group 16 elements will form ions with a charge of -2.
