___________                                                                                                                      TODAY’s NOTES:

IONIC BONDs (electrovalent)- Ionic solids → Salts (Crystals of ions): 

Occurs between ions and these ions are produces by a REDOX REACTION that occurs due to a transfer of electrons.

Almost every case of ionic bonding occurs between a metal and nonmetal because

THE DIFFERENCE BETWEEN ELECTRONEGATIVITY IS LARGE ( ≥ 1.7) 

and thus a transfer of electrons occurs!

 

Covalent BONDs Molecular solids → Molecules of finite particles: 

  Occurs between Nonmetals and they occur due to the sharing of electrons.

  Almost every case of covalent bonding occurs between a nonmetal and nonmetal because

THE DIFFERENCE BETWEEN ELECTRONEGATIVITY IS SMALL ( 0 – < 1.7) 

and thus electrons are shared!

Nonpolar Covalent Bond = electrons shared equally: Difference of electronegativity = 0 – 0.4.

Polar Covalent Covalent Bond = electrons shared unequally: Difference of electronegativity = > 0.4 to <1.7
