A
Fe > Ti > Mn
2
Q
GR. group 8 in periodic table consists of three columns?
A
Group 8 elements are differing from the other transition elements of B in their properties, in which these elements are similar horizontally more than vertically (more than the elements below in the same column
3
Q
GR. Chromium and copper are anomalous from the expected electronic configuration?
A
DUE TO extra stability of half filled 4s and half filled 3d in chromium atom Cr:[Ar] , 4s1 , 3d5
& extra stability of half filled 4s and completely filled 3d in copper atom Cu:[Ar] , 4s1 , 3d10
