When a metal loses electrond it becomes?
Metal atoms become ions when they lose electrons.
What gas is produced when acid corrodes metal?
hydrogen
What does the term base or parent metal in an alloy mean?
base metal: a metal that oxidises or corrodes easily and i dont know what parent metal is..
Do metal atoms decrease in size when they combines with nonmetal atom?
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.
What things corrode metal?
Corrosion of metal is caused by oxygen or oxidising substances, salty water and some medium strong acids
When a metal loses electrond it becomes?
Metal atoms become ions when they lose electrons.
What metal corrodes easily to form rusty oxide?
This metal is iron.
What gas is produced when acid corrodes metal?
hydrogen
Why does alcohol eat away metal?
The acidity of the alcohol corrodes the metal, "eating away" at it.
Is uranium more likely to lose or gain electrons?
Uranium loose electrons becoming a cation.
Is there any metal that corrodes less than platinum?
gold
Why is platinum used for pacemakers?
platinum is a metal that never corrodes
What does the term base or parent metal in an alloy mean?
base metal: a metal that oxidises or corrodes easily and i dont know what parent metal is..
How many electrons will the metal sodium atoms lose when the metal reacts with a nonmetal?
Sodium loses one electron when it reacts with a nonmetal.
Do metal atoms decrease in size when they combines with nonmetal atom?
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.
DOES platinum gain lose or share electrons?
Since platinum is a metal it will tend to lose electrons.
What are three differences between ionic bonds and covelant bonds?
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.
