Question

State two reasons for the following facts-

a) Sulphur is a non-metal

b) (ii)Magnesium is a metal

One of the reasons must be supported with a chemical equation.​

Answer 1

Answer:

the answer of A) only

Explanation:

Number of electrons in the valence shell is more than 4 i.e., 6 unlike metals which have valence electrons less than 4. (2) It has tendency to accept electrons. (3) It is non-lustrous. (4) It burns in air to form sulphur dioxide which is an acidic oxide as non-metals react with air to form acidic oxide.

Answer 2

Answer:

a. I) because it is neither malleable nor ductile. it is brittle.

ii) It does not conduct electricity or heat.

b. I) it is malleable and ductile means it can be beaten to form thin sheets and wires.

ii) it conducts heat as well as electricity.
