electrons
Metal atoms become ions when they lose electrons.
hydrogen
base metal: a metal that oxidises or corrodes easily and i dont know what parent metal is..
As metals have to become metal ions in order to chemically combined with nonmetals they have to lose their valance electrons. This process is associated with making the atoms smaller.
Corrosion of metal is caused by oxygen or oxidising substances, salty water and some medium strong acids
Metal atoms become ions when they lose electrons.
This metal is iron.
hydrogen
The acidity of the alcohol corrodes the metal, "eating away" at it.
Uranium loose electrons becoming a cation.
gold
platinum is a metal that never corrodes
base metal: a metal that oxidises or corrodes easily and i dont know what parent metal is..
Sodium loses one electron when it reacts with a nonmetal.
As metals have to become metal ions in order to chemically combined with nonmetals they have to lose their valance electrons. This process is associated with making the atoms smaller.
Since platinum is a metal it will tend to lose electrons.
Ionic bonds are formed between metal atoms and non-metal atoms. The metal atoms lose electrons and form positive ions, but the non-metal atoms gain electrons and form negative ions. Since the atoms both now have opposite charges, they are attracted to each other and form an ionic bond.However, covelant bonds are formed between two or more non-metal atoms. The atoms share electrons rather than losing or gaining electrons from each other.
