If Kb for NX3 is 3.0×10−6, what is the percent ionization of a 0.325 M aqueous solution of NX3?

They carry out the exchange of gases as we breathe ( oxygen and carbon dioxide).

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts
