Question

how many valence does nitrogen have

Answer 1

You can refer to your periodic table for that. If the P-orbital can fix a maximum of 6 electrons, and you have 2 already from the s-orbital, and carbon has 4 (2 from s and 2 from P). Then how much do you think Nitrogen has?

Answer 2

so you have to add them up

Answer 3

Yes.

Answer 4

12

Answer 5

Nitrogen = [He] 2s^2 2p^3
2+3=5
Valence electrons = 5

Answer 6

No. It might also be easier if you just looked at the group number and subtracted 10 from it. Which would be 5. If you notice, it's group 15 - 10 = 5

Answer 7

well i learned it that way :P you could also just count in the row where the element is from left to right. So lithium=1, beryllium=2, boron=3, carbon=4 and nitrogen=5
