In this problem, we're looking at electron configurations, and specifically we're looking at boron.
00:07
Now, this is a way to show how we have electrons filling orbitals from lowest energy to highest energy for a specific element.
00:19
And we use our periodic table.
00:23
So remember we have s, p, d, and then f.
00:31
S can have up to two electrons.
00:33
P can have up to six, d up to 10, and f up to 14.
00:40
So we start by saying, all right, we're beyond hydrogen, and we're beyond helium...
