Question

Q 1 :Which meral or non-metal has the smallest difference between its melting
point and its boiling point?
Q 2: Which metal or non-metal has the largest difference between its melting point
and its boiling point?​

Answer 1

Answer:

Q1.The halogens have low melting points and low boiling points. This is a typical property of non-metals. Fluorine has the lowest melting and boiling points.

Q2. Tungsten has the highest melting point where as silver has low boiling point. Sodium and potassium have low melting points. Non metals have low melting point.

Explanation:

Answer 2

1) Helium. The melting point is -272.2C and the boiling point is -268.9C, a difference of only 3.3C! Wear your thermal undies if you want to measure those temperatures in person!

2). Tungsten has the highest melting point where as silver has low boiling point. Sodium and potassium have low melting points. Non metals have low melting point.
