Answer 31

Please don't mass tag... not only is it a huge headache for me, but it's also against the rules here.

Answer 32

You can easily find The number of valence electrons by looking at the vertical columns of the periodic table elements that are in the same group, all have the same number of valence electrons. the number of valence electrons are the ones farthest from the nucleus and least tightly held.

Answer 33

I think D is right but not sure

Answer 34

but...
I need help and I do not have the time to wait for 2-5 days for some1 2 help me

Answer 40

elements in the same column of the periodic table have the same number of valence electrons

Answer 41

@MikeyMaximum If you notice Sodium Na,Hydrogen H, and Francium, Fc are in the same vertical column or group so they have the same number of valence electrons.

Answer 42

so...
