Types of elements:
(i) Metals-
Metals are the elements which form verifying ions by losing electrons. The metals are good conductors of heat and electricity. They are malleable and ductile and possess high density. The oxides of metals are basic in nature.
(ii) Non-metals-
Non-metals are the elements which form negative ions by gaining electrons. 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 part in chemical reactions.
Molecule-
Molecule is the ultimate particle of an element or a compound which exists in a free state but does not take part in chemical reactions.
Oxidation-
Oxidation is a process of gaining oxygen (or each other electronegative element) or removal of hydrogen (or electro confirmatory element). Non-metals are reducing agents.
Reduction-
Reduction is the addition of hydrogen (or any other electropositive element) or removal of oxygen (or any electronegative...If you want to get a full essay, order it on our website: Orderessay
