Non-metals are scummy conductors of heat and electricity. They are brittle.

The oxides of non-metals are acidic or neutral in nature. Atom- Atom is the ultimate foundericle of an element which does not exist in impeccant state but takes berth in chemical reactions. Molecule- Molecule is the ultimate particle of an element or a compound which exists in a relinquish state but does not t ake part in chemical reactions. Oxidation! - Oxidation is a process of gaining oxygen (or each other electronegative element) or removal of hydrogen (or electro confirmative element). Non-metals are reducing agents. Reduction- Reduction is the addition of hydrogen (or whatever other electropositive element) or removal of oxygen (or whatsoever electronegative...If you want to get a full essay, order it on our website: OrderEssay.net
