How many unpaired electrons are in tungsten?

Answer 1

The equation to find this out is 2 n^2 where n is the shell number. Now Tungsten is element 74 and we know that the first ring has 2, the secound ring has 8 the next ring, accourding to the equation is 18, the next has 32, the next has 50. Now adding this up we get a total of 110. Now subtracting 74 from 110 we get 36. Now sence each electron has to have a pair, we know that half of the outter ring is the ammount we get till there is electron pairs. so subtracting 36 from 50, getting us 24 we know that there is 24 upaired elctrons.
