How many bonds can nitrogen have? Which rule or principle should be used? A) Five bonds; octet rule. B) Three bonds; octet rule. C) Three bonds; the Hund's rule. D) Five bonds; the Aufbau Principle. correct answer: B When two hydrogen atoms meet, they will attract to each other and form a bond (and a H2 molecule). Why? A) Because electrons like to stay together. B) Because electrons like to be paired up. C) Because there is attraction between the electron in one hydrogen atom an...
