If a diagonal line is drawn in Mendeleev's periodic table from left to bottom right, the elements below the diagonal will be:
Metals
Non-metals
Metalloid
Transition metals
As we learnt in
Mendeleev's periodic table -
Mendeleev arranged the 63 discovered elements in the periodic table in to 7 horizontal rows known as periods and vertical column is known as groups numbered 1 to 8.
-
In the Mendeleev periodic table, the metallic character of metals increases down the group and decreases along the period. So, the metals occupy the bottom left corner part till the diagonal in the middle.
