What is the number of electrons shared between the atoms in a molecule of nitrogen, N2?

August 2019 NY Regents Chemistry Exam

12 What is the number of electrons shared between the atoms in a molecule of nitrogen, N2? (1) 8

(2) 2

(3) 3

(4) 6


Solution: Nitrogen can be found on the Periodic Table. Its electron configuration is 2-5 which means it has 5 valence electrons. Each element (other than H and He) wants eight valence elections. Nitrogen needs three more electrons to have eight. Therefore, a nitrogen atom will bond with another nitrogen atom via a triple bond. Each bond has 2 electrons. Triple bond has 2*3= 6 electrons
