An element with Z = 48  belongs to……period of modern periodic table

Hints to predict the position of element in the Modern periodic table :1)Elements from Z = 58-71……Lanthanoids…..4f series….6th period……3rd(IIIB) group;2)Elements from Z = 90-103……Actinoids…..5f series….7th period……3rd(IIIB) group;3)Elements from Z = 104-118………..Last two digits gives group number….. 7th period;4)Elements from Z = 31-57….subtract 18 to get preceding element;5)Elements from Z = 72-89….subtract 32 to get preceding element;6)Elements from Z = 104-120….subtract 32 to get preceding element ;For Z=104-120….simplest Hint7)Elements from Z = 104-120….subtract 82 to get a lower member(Z<30) belonging to same group;Hints 4, 5 and 6 can be used repeatedly until an element belonging to same group with Z < 30 is obtained;Elements with Z < 30 with their group, period and block can be known from Electronic configuration;Ex : Z=112, 80, 48, 30….belong to 12th(IIB) group;(112-32)=80; (80-32)=48; (48-18)=30;(n-1)d1-10ns1-2 ;Note : Many elements of d-block have anomalous configuration. So only GEC of each group is highlighted;Z = 30…….Zn…  4s23d10…..n=4…..4th period…..d-block….……12th group;Z = 48…….Cd………….….….n=5….5th period……d-block……...12th group;Z = 80…….Hg…………..…….n=6….6th period……d-block…..…12th group;Z = 112……Cn…………..…….n=7…7th period……..d-block..…..12th group;
