Tin is unaffected by air at ordinary temperature due to its?

A. Low melting point
B. Weak electropositive character
C. High boiling point
D. White lustrous appearance

Correct Answer:

Option A – Low melting point

Explanation

Tin has a melting point of 232° which enables it to be unaffected by air at ordinary temperature coupled with the fact that it also helps in making a good metal for alloying.

Tin is relatively unaffected by both water and oxygen at room temperature due to its low melting point. It does not rust, corrode, or react in any other way. This explains one of its major uses: as a coating to protect other metals.
