Answer 1

Answer:

Explanation:

Chemical Properties of Metals

The density of metals is usually high.

Metals are malleable and ductile.

Metals form an alloy with other metals or non – metals.

Some metals react with air and corrode. ...

Metals are good conductors of heat and electricity. ...

Generally, metals are in a solid state at room temperature

Answer 2

Explanation:

Metals react with oxygen to form metal oxides. Metals donate electrons to oxygen for the formation of metal oxides. For example,

4K + O2 → 2 K2O

Metals like sodium and potassium are highly reactive. They react with water to form alkalis such as sodium hydroxide and potassium hydroxide.

2Na + 2H2O → 2NaOH + H2

Calcium also reacts with water to form calcium hydroxide and hydrogen.

Ca + 2H2O → Ca(OH)2 + H2

Whereas, magnesium and zinc do not react with cold water. They form their respective oxides when reacted with hot water.

Mg + H2O → MgO + H2

Iron is less reactive than sodium, potassium, calcium, zinc and magnesium. It does not react with cold and hot water, but it reacts with steam to form magnetic oxides.

3Fe + 4H2O → Fe3O4 + 4H2
