Electron Configuration

What is Electron Configuration? The arrangement of electrons in an atom

What do I need? Energy Level (1-7) Orbital (s,p,d,f) How many electrons 1 s 2

Energy Levels 1st energy level: 2 2nd energy level: 8 3rd energy level: 18 4th energy level: 32

Orbitals Orbital: three-dimensional space around the nucleus that is the probable location of an electron s  holds a max of 2 p  holds a max of 6 d  holds a max of 10 f  holds a max of 14
