So let us start.
00:05
In group 13, there are, so in group 13, the elements will have three valence electron in the outermost shelf.
00:21
We have indium with the positive charged.
00:27
Hence, indium with the positive charge means that indium have lost one of its electron.
00:35
That means there will be a total of 2 valence electron in the automo shell.
00:41
The structure can be represented as i .n.
00:44
1, 2 with a positive sign.
00:48
Second, we have group number 17.
00:52
That means they have total of 7 valence electron.
00:56
Iodine with the negative charge means that it has gained a 1 electron.
01:04
So the total electrons will be 8...
