Answer:
Valence electrons H2=2
Valence electrons NH3=8
Valence electrons CH4=8
The attached figure shows the electron structures of each compound.
Explanation:
The valence electrons of each molecule will be calculated first. And this is equal to the sum of the valence electrons of the atoms in the molecule.
Valence electrons H2=2*H=2*1=2
Valence electrons NH3=(1*N)+(3*H)=(1*5)+(3*1)=8
Valence electrons CH4=(1*C)+(4*H)=(1*4)+(4*1)=8
