i)Two elements which have their outermost shell complete are:
He[which has 2 electrons in outermost shell and is complete]
Ne[which has 8 electrons in outermost shell and is complete]
ii)Two elements which have outermost shell incomplete are:
Li [which has 1 electron in outermost shell
Na[ which has 1electron in outermost shell{2,8,1}]
iii)Two elements which have two outermost shells complete
Ne[ which has {2,8} electrons , complete two outermost shells]
Ar [which has {2,8,8} electrons , complete two outermost shells]
iv)Two outermost shells incomplete :
Fe [[which has the atomic number 26,{2,8,14,2}with two electrons in the outermost shell.]
Mn [ which has the atomic number 25,{2,8,13,2}with two electrons in the outermost shell.]
v)One electron short of octet: Fluorine [which has the configuration {2,7} and there is one electron less from the octet configuration {2, 8}
vi) Two electrons in the outermost orbit: Fe [which has the atomic number 26,{2,8,14,2}with two electrons in the outermost shell.
Hope this helps you....:)
