Hello everyone, let's start the question.
00:02
In this question we are given with some free iron terms for which we need to determine the values of l, m, l, m, s and s.
00:11
So basically, if we write in general when we are given with such notation, let's say we have 2 s plus 1 l.
00:24
This is a general notation for expressing any atom term symbol.
00:28
Where s stands for the spin and 2s plus 1 is the total spin and l stands for the angular momentum value.
00:50
So if the value of l is equal to 0 then the symbol which is used is s.
01:03
For l equal to 0, symbol used is s.
01:07
When the value of l is 1, then the symbol use is p, when the value of s is 2, then the symbol used is d.
01:18
When the value of l is 3, then the symbol used is f, and when the value of l is 4, then the symbol used is g.
01:28
Now let us take into consideration the first part of the question that we have as 2d.
01:35
So if we compare it from the general notation, we will get the value of 2s plus 1 is equal to 2.
01:43
If we solve it further, we will get the value of 2s equals 2 1 which implies s is equal to plus minus half...
