1) Mn
2) At
3) Cl, Fe, Sr, Cs
4) Increase
5) F, N, Be, Ba
6) Cu
7) Fr
8) Ca, Zn, P, Ne (assuming it has one) or it could be first assuming did not have one
9) Be -> B , IE decrease due to decrease CF since valence electron is in p block for B and s block for Be. p block is further from nucleus than s block so less CF
or
N -> O IE decreases due to decrease CF since one electron in the p orbital of O that has 2 electrons (e--e- repulsion in an orbital) is further from nucleus than N so less CF
10) see your notes
11) Across a period, the CF increases
