Reaction with oxygen
Burn readily to form oxides
Burn if finely divided to form
oxides
Become coated with oxide
layers during heating
Reaction with water
Reaction with cold water to form
hydroxide and hydrogen gas
Reaction with dilute acids
React with cold dilute acids to
form hydrogen and salts
Hot water- oxide and H2
Reacts with steam when heated
strongly to form oxide and
hydrogen gas
No reaction
React with warm dilute acid to
form hydrogen and salts
No reaction
No reaction
