E is Bohrs model the dots on the rings represent the valence electrons
I believe c is the right answer.
Your answer is B. 6.02 x 1023 grams
Atomic mass Cu = 63.546 a.m.u
63.546 g ---------------- 6.02x10²³ atoms
22 g --------------------- ??
22 x (6.02x10²³ ) / 63.546 => 2.08x10²³ atoms
hope this helps!
