Hope this helped!
The number of electrons in an atom's outermost valence shell governs its bonding behaviour.

I can’t see the picture but a atom I think
Answer:
Oi ima french Not really
Explanation:
7-7 = 0 andbecause it is so ima done
37.8 g CH2Br2 X (1 mol CH2Br2 / 173.83 g) = 4.60X10^-3 mol CH2Br2
<span>4.60X10^-3 mol CH2Br2 X (2 mol Br / 1 mol CH2Br2) X 6.02X10^23 atoms/mol = 5.54X10^21 bromine atoms.
I think this is the answer.</span>
