Feliz [49]3 years ago
3 0

Answer:

F - Cl - Br - I - At - Ts

Explanation:

All the halogens, are the elements that forms a ion with a -1 charge.

The elements from group 17 in the Periodic Table are the one that has 7 electrons of valence. They need only 1 e⁻  to have the closest noble gas conformation so, they can comply with the octet rule.

This is an example:

Cl₂ (g) + 2e⁻  →  2Cl⁻

Chlorine which is a diatomic gas, gains 2 electrons to make 2 moles of chloride (in order to the balance the reaction)

Which of the following processes would you predict to have an increase in entropy?
Anna [14]
C. Melting ice. 
It is C because melting ice is a change of state from solid to liquid which requires an addition of energy(or entropy) into the system.
Condensation of water occurs from a gas to a liquid state, which takes energy out of the system(water) and gives it to the surroundings(air around it). Freezing water is the same as condensation except for the state change. Deposition is simply gas to a solid instantaneously so you can again see it as with the other two examples.
