What 2+ ion has the following ground state electron configuration?Explanation / Answer
31)
raddi increases as we go down and incraeses as we move to right
Answer: b
32)
SO32- is terahedral as S forms 3 digma bond and has a lone pair
so bond angle would be 109.5 o
Answer: e
33)
ml = 0 is for s orbital
where only 2 lectrons can reside
