2. Complete the back of todays worksheet.
Molecule Ion Attractions – (ION – Dipole) are the attractions a positive or negative ion has for a polar molecule (water) THAT will Dissolve the ion from its crystal of ions and create a solution (aq) = homogeneous mixture!
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
