Question

calculate how many valence electrons are in H2CO, N2, Cl2?

Answer 1

In H2CO, C is bonded to H, H and O. Write down the valence electrons of each element. 2 H = 1x 2 = 2. C= 4 O = 6 Total 12 

Answer 2

In H2CO, C is bonded to H, H and O.  Write down the valence electrons of each element.2 H = 1x 2 = 2.C= 4O = 6Total: 12
