(4) F2(g) is your answer, since gases have the highest entropy of all the three basic states of matter (yes, by this I am excluding plasma -_-)

Answer: Option (4) is the correct answer.

Explanation:

STP means standard temperature and pressure, that is, at STP temperature is 0 degree Celsius, volume is 22.41 L, and pressure is 1.00 atm.

Entropy means that degree of randomness, that is, particles of a matter will move rapidly from one place to another.

In gases, molecules move randomly as they are held by weak Vander waal forces.

Thus, out of the given options, at STP, a sample of [tex]F_{2}(g)[/tex] element has the highest entropy.
