3 valence electrons are transferred in the formation of the compound potassium nitride because nitrogen needs 3 valence electron to become stable, or to have the electron configuration of noble Gases.
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.

The substance that needs more energy to undergo an increase of 25°C will
have a higher specific heat, because energy depends directly on
specific heat.
Q = cm∆T
where c = specific heat of the substance,
m = mass
∆T = temperature difference </span>
Ion is an atom or molecule with a net electric charge due to loss or gain of one or more electrons.
