NCERT Class XI Chemistry
What are the major differences between metals and non-metals?
Solution in Detail
(video solution below this)
There are 95 (78%) metals in the periodic table.
There are 17 non-metals in the periodic table.
Metals [except Hg, Cs, Ga] have high melting and boiling points.
Non-metals [except Carbon and Boron] have low melting and boiling points.
Metals are good conductors of heat and electricity. Non-Metals are bad conductors of heat and electricity.
Metals are malleable and ductile, but non-metals are brittle.
Location in Periodic Table
Metallic character is the strongest in elements on the lower left corner of the periodic table.
non-metallic character is the strongest in elements on the top right corner of the periodic table.
Metals are less electronegative. They easily lose valence electrons, i.e., get oxidized.
non-metals are highly electronegative. They have a strong tendency to gain electrons.
Metallic oxides are basic and ionic.
non-metallic oxides are acidic and covalent.
Metals form cations in aqueous solutions.
non-metals form anions, and oxyanions in aqueous solutions.
