What is the purpose of bonding?
The purpose is to acheive stability (stable octet).
Explain what pure covalent bonds are and their method of bonding.
Non-metal atoms only bond through equal sharing of electrons.
Explain what polar covalent bonds are and their method of bonding.
Electrons are unequally shared. The more electronegative atom has the greater pull of the electron.
Explain what ionic bonds are and their method of bonding.
The transfer of electrons from a metal to a non-metal ion. The electrostatic attraction of the two oppositely charged ions bonds them together.
Explain what metallic bonds are and their method of bonding.
Metal cations and electrons float in a sea.
What are polar molecules? What are the qualifications for a molecule to be polar?
They are asymmetrically shaped molecules and have at least 1 polar covalent bond.
What is range of ΔEN of Pure covalent bonds?
What is the range of ΔEN for polar covalent bonds?
What is the range of ΔEN of ionic bonds?
1.7 to 3.3
Name the 5 shapes of polar molecules.
Linear, angular or bent, trigomal planar, trigomal pyramidal, tetrahedral.
