Hi, in this question we are shown with these atoms and we are asked to select the one which can form a cation with charge plus one.
00:10
We are given with these electrons around the nucleus for each atom we have to distribute in the respective subshells.
00:19
Here we can see we are having this nucleus and two electrons in the first ring and there are electrons in the next ring.
00:30
We will distribute in this manner as we will put two electron in 1s orbital and then we will take 2s orbital we can put two electrons in that after that we are left with one two three four five six.
00:43
These we will put in 2p orbital in this manner.
00:46
Here we can see we are having the electronic configuration which is fully filled therefore it is not possible to remove electron and it is stable hence we will not remove electron hence it is not the correct answer.
01:01
In second we will fill electron as 1s2 2s2 2p2.
01:09
Here we require one more electron to form a half filled configuration therefore we can say this is not going to remove the electron as it will not make it stable.
01:25
If we talk about this third one we can fill the electron as 1s2 2s2 2p5...
