Question

How to calcluate the amount of energy released with electron gain enthalpy?

Answer 1

Answer:

=> Actually, Energy is released when an electron is added to the atom. Therefore, the electron gain enthalpy is negative. The electron gain enthalpy for halogens is highly negative because they can acquire the nearest stable noble gas configuration by accepting an extra electron

Thanks ☺️❤️

Answer 2

Answer:

You can calculate amount of energy released by the formula

Q= mc ∆T

where,

m is mass

c is specific heat and

∆T is change in temp.

Explanation:

As energy released when electron is gained that is always -ve .

So it must be negative.

Hope this is helpful.
