WHAT THE HECK DO I NEED TO BE ABLE TO DO? CONTENT OBJECTIVE WHAT THE HECK DO I NEED TO BE ABLE TO DO? express the arrangement of electrons in atoms through electron configurations. I can

Electron Orbitals 1. The arrangement of electrons in an atom is known as the atom’s ___________ _________________. One type of electron configuration is _________ ___________. Electron configuration orbital notation

Electron Configurations A. The periodic table holds the answer for the order in which electrons ____ orbitals. 1. Always start at ___________ and then move through the periods (rows) until you arrive at the desired element. fill hydrogen
