Hello, this question it is based upon the electronic configuration.
00:07
So here electronic configuration means electronic configuration that means the distribution of the electrons of an atom or molecule in atomic or the molecular orbitals.
00:23
So here we have that is argon 4s2, 3d10, 3d10 and 4p.
00:40
5.
00:41
As we can see here that is the valence electron is 5 here that of the p orbital that means the element will be of the p orbital.
00:50
Now this is the short -hand electronic configuration.
01:00
That means here into this electronic configuration we have included the electronic configuration of the argon.
01:12
So therefore now let us see the electronic or the atomic number of the argon is 18 that means it consists of the number of protons or the electrons in this case is 18 so here this argon so we do not need to write down the whole configuration but for but for better understanding we can write it down that is neon 3 s2 3p 6 this is how we write down the short -hand electronic configuration by including.
01:58
For example, for the electronic configuration of the neon, it is helium 2s2 -2p6 and then 3s2 3p6.
02:09
And we know that the helium is 2, 1s2.
02:15
This is 1s2, 2s2, 2p6, 3s2 3s2 3p6.
02:22
So this is the electronic configuration...
