About this document
Metals and Non-Metals Overview for Class 8 by Rahul Mishra is a document available to read on EtoBox.
There are 118 total elements, some of which are metals and non-metals. Metals are hard, lustrous, malleable, ductile, sonorous, and good conductors of heat and electricity, while non-metals are soft, dull, break into powder, non-ductile, non-sonorous, and poor conductors. Metals react with oxygen to form metal oxides, react with acids to form salts and hydrogen gas, and can displace less reactive metals in salts. Non-metals may react with oxygen but not water or acids, and reactions with bases are complex.
