how were the positions of cobalt and nickel resolved in modern periodic table?

answered-by-expert Expert Answer

Both of them are transition elements. These are characterised by the filling of inner d orbitals by electrons and are therefore referred to as d-Block Elements. Hence they are placed in d block elements.

You will study about d orbitals and transition elements in higher classes.
