Hello students, let's begin with this question.
00:03
Here this first part, this is based upon the ionization energy.
00:08
So this is the energy, energy that is required to remove an electron from the valence shell.
00:28
So now here we have to write down the increasing ionization energy.
00:32
So first one is chlorine and bromine.
00:36
So here out of chlorine and bromine, here both these are the, both are the halogens and here the bromine will have the higher atomic number than the chlorine.
00:51
So here the bromine has the higher ionization energy than the chlorine.
01:01
The second one is the, second one is the radium, then beryllium and magnesium.
01:12
So here the order is the, here the order is, firstly comes the radium will have the lower ionization energy than magnesium, than the beryllium as it will have the, so here, here next one is the, in the second part, this part is based upon the electron affinity.
01:37
This is the amount of energy required, energy required to add or gain an electron.
01:51
So now here the a part is out of from the sodium, lithium and potassium.
01:57
Here the order is that potassium will have the lower electron affinity than the sodium, than the lithium.
02:04
Then in the b part is out of sr, strontium, tin and the terellium.
02:11
Here the order is that terellium will have the lower electron affinity than the tin, than the strontium.
02:18
Now here in the, so here in the next part again we have to write down the electron affinity order.
02:25
So this order is between the, here this is between the magnesium, phosphorus, chlorine, bromine and the, here is the, here is the iodine...
