Ionization Energ​

Answer 1

Answer:

A quantitative measure of the tendency of an element to lose electron is given by its Ionization Enthalpy.  It represents the energy required to remove an electron from an isolated gaseous atom (X) in its ground state. The first ionization enthalpy generally increases as we go across a period and decreases as we descend in a group.

a) In K and Br,K is metal and it's very easy for metal to loose an electron whereas it requires very high energy for a non-metal to loose an electron.

b) In S and Te,S requires more energy to loose an electron because ionisation enthalpy decreases as we descend in a group due to the decrease of the hold by nucleus on the outermost electron.

c) In Ga and Se,Se requires more energy more energy to loose an electron because ionization enthalpy increases as we go across a period.

d) In Ne and Sr,Ne requires much more energy because it is in most stable configuration and it will take very high energy to make Ne lose an electron.
