Explain how electron configuration affects an element's location on the periodic table?

well EC plays a major role in determining the grp, period and block of an element....
block-the last electron give the block
period-the highest principal quantam no. give the period no.
group-for s block the sum of all electrons present in the valance orbital give grp no.
for p block the no of valance electrons +12
for d block no. of electron predent in d orbital+2

ex-sodium-1s2 2s2 2p6 3s1=s block,3 period,1 grp
titanium-1s2 2s2 2p6 3s2 3p6 4s2 3d2=d block,4 period,4 grp
flourine-1s2 2s2 2p5=p block,2 period,17 grp
