Hund's Rule

Every orbital is singly occupied with one electron before its doubled

names of sublevels

s, p, d, f

1s sublevel

sphere shape

closest to the nucleus

least amount of energy

"p" sublevel shape

teardrop/ dumbell

how many electrons can each orbital hold?

2

how many orbitals are in an "s" sublevel?

1 orbital, so it can hold 2 electrons

how many orbitals are in a "p" sublevel?

3 orbitals, so it can hold 6 electrons

how many orbitals are in a "d" sublevel?

5 orbitals, so it can hold 10 electrons

how many orbitals are in a "f" sublevel?

7 orbitals, so it can hold 14 electrons

electron configuration notation

number= energy level

letter= sublevel

little number= number of electrons in the sublevel

the 4s sublevel comes BEFORE ___

the 3d sublevel

goes in order: 3s, 3p, 4s, 3d, 4p, 4d, 4f
