b) Among non-metals, carbon has the highest melting point.
c) Hydrogen is the most abundant element in the universe.
d) Oxygen is the most abundant element in the earth's crust.
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
a) Mercury is the only metal that exists as liquid at room temperature. It is correct statement because it is a liquid metal. b) Among non-metals, carbon has the highest melting point because diamond is the allotrope of carbon which is very hard in nature and has high melting…
