Question

When metal combined withoxygen

Answer 1

Answer:

When metal combined with O² it form metal oxide . It is basic in Nature .

some are also Ampotheric that has both nature of acid and base .

Answer 2

Explanation:

Metals react with oxygen to form metal oxides.

• These metals are basic in nature.
• They generally combine with oxygen by loosing electrons .
• Metals loses electrons to form cations.
• oxygen takes electrons to form anions .
• when metals reacts with oxygen the process of oxidation takes place.
• This reaction gives a lot off heat .
• Platinum is a metal which doesn't react with oxygen even at high temperatures.

Example :-

1. Iron burn in oxygen to become red hot and sparks .
2. Metals such as potassium, sodium and lithium react with oxygen very quickly.
3. Metals like copper and mercury react with oxygen very slowly and need to be heated continuously in order to see this happening.
