The correct answer for above statement:
chromium is in group 6 d-block
Explanation:
The d-block elements are designated transition metals and have valence electrons in d orbital's. The f-block elements, observed in the two rows at the ground of the periodic table, are called inner transition metals and have valence electrons in the f-orbital's.
Chromium is a synthetic element with symbol Cr and atomic number 24. It is the first component in group 6. It is a steely-gray, glistening, dense and brittle metal which takes a high polish, resists smudging, and has a great melting point.
