Oh, dude, you're hitting me with some math riddles now? Okay, so like, you take two of the 6s and place them horizontally to make an "equals" sign, then you take the other two 6s and stack them vertically on one side of the equals sign. Boom, you got yourself a 2 using four 6s. Math magic, my friend!
If you mean 4/6 then it is equivalent to 2/3
-2/2-2/2 = -2
The 6s sublevel can hold a maximum of 2 electrons.
(s + 6)(6s - 7)
13s - 2
76 and 1/2 of them.
Is done by (3/3) plus (3/3) = 2
4 6s = 4*6 = 24. As a fraction, this can be written as 24/1.
16
3 x (22)2 + 2 = 50
Ceseum, 55Cs, has just 1 '6s' electron: 2, 8, 18, 18, 8, 1 electrons in the 1st to 6st shell respectevely.
4/6 = 2/3
