Differentiate between metals and non-metals ??
Answers
metals r good conductor of heat and electricity,but non metal do not.
Differences on basis of chemical properties :
Ф The metals have 1,2 or 3 electrons in their outermost shell.
Ф The non-metals have only 4,5,6 or 7 electrons in their outermost shell.
Ф The metals lose electrons only.
Ф The non-metals gain electrons.
Ф The metal always has a positive charge.
Ф The non-metals has a negative charge.
Ф Metal elements form cations.
Ф Non-metal elements form anions.
Ф Metals are found abundant in the bottom of the periodic table.
Ф Non-metals are abundant at the top of the periodic table.
Differences on basis of physical properties :
Ф Metals are mostly solids.
Ф Non metals are mostly liquids or gases .
Ф Metals are sonorous and ductile .
Ф Non-metals are non-sonorous and not ductile.
Ф Metals are malleable .
Ф Non metals are non-malleable .
Ф Metals have high melting and boiling points.
Ф Non-metals have low melting and boiling points .
