METAL
Physical Properties Of Metals
metals are electropositve ions
conducts heat and electricity
posseses lusture
are melliable
are ductile
they act as reducing agent and can have 1,2,3 electrons in their outer shell as metals can lose electrons
most abundant metal is Al (7) and Fe(4)
As metals are very tightly paked so no. of atoms per unit volume are very high so they have a higher density
as metals have free electrons and when light fallson metallic surface then these free elec. absorbs photons of light and start vibrating and releases energy in the form of light
Chemical Properties Of Metals
metalsare electropositive elements
metals are good redcing agents
metals reacts with oxygen quckly and lose their shiny surface exception is gold and silver
metals+o2 gives metal oxide
metalsreacts with water to form hydroxides exception are gold and platinum
metal+H2O gives metalhydro oxide+H2
metal+H2O gives metal oxide+H2
metals react with dilute acids to form metal salt andH2
metals+dilute acids gives mteal salts+ H2
