Hello student we have to draw the molecular orbital diagram of the ionic species h .e.
00:05
2 plus.
00:06
Okay.
00:07
So, h .e .2 plus.
00:13
We know that the atomic number of helium is 2.
00:17
Okay, atomic number of helium is 2.
00:19
So here the total number of electrons in h .e2 plus will be, there are 2 helium atoms here.
00:25
Okay.
00:25
So 2 plus 2, 4 electrons and here is a positive charge.
00:30
That is, there is a donation of 1 electron.
00:33
So the total number of electrons in this ionic species will be three electrons.
00:39
Okay, three electrons.
00:40
So now we have to write the molecular orbital -wise electronic configuration.
00:45
Okay, that is sigma 1 as 2, sigma star 1s 1...
