Question

how many valence electrons do each of the following species contain? 1st attempt part 1 (1 point) n2 valence electrons part 2 (1 point) no valence electrons part 3 (1 point) hbr valence electrons part 4 (1 point) no+ valence electrons

Explanation:

Step1: Determine N valence electrons

N is in group 15, has 5 valence electrons. For N₂, 2×5 = 10.

Step2: Determine N and O valence electrons for NO

N has 5 valence electrons, O in group 16 has 6. So 5 + 6=11.

Step3: Determine H and Br valence electrons for HBr

H in group 1 has 1 valence electron, Br in group 17 has 7. So 1+7 = 8.

Step4: Determine N and O valence electrons for NO⁺

N has 5, O has 6, total 5 + 6 = 11. But +1 charge means 1 electron less, so 11- 1=10.

Answer:

Part 1: 10
Part 2: 11
Part 3: 8
Part 4: 10
