Chemical Bonds 2) Covalent Consider 2 close Cl atoms, each = 1s 2 2s 2 2 p 6 3s 2 3p 5 If draw closer until overlap an outer orbital, can share whereby 2 e - fill the remaining 3p shell of each Cl Low energy condition causes electrons to stay overlapped; results in a strong bond  Cl 2 This is the covalent or shared electron bond Usually stronger than Ionic bond
