Octate rule refers to the tendency of atoms to prefer to have 8 electrons in the valence shell.
00:07
So the valence shell, the automost shell, should be completely filled.
00:12
Now, first of all, we have.
00:17
So, first of all, gallium.
00:22
So here, gallium, that is ga, this is the symbol.
00:27
So for this, the atomic number is 31, and that's why the electronic configuration will be.
00:37
Argon 3d10 4s2 4p1 so argon is the noble gas with 18 electrons then 10 plus 2 plus 1 so there will be 31 electrons so now in the outermost shell that is fourth shell we have total of three electrons right so to obey octet rule gallium loose is three electron.
01:22
So three electron has to be lost in the case of gallium.
01:26
Now second part, oxygen.
01:38
So here we have oxygen atom and the atomic number is 8.
01:44
So the electronic configuration will be 1s2, 2s2, 2p4.
01:54
So the automost shell has 4.
01:57
In the p subshell, so maximum 6 electron can be filled...
