Unit 4: Chemical Bonding

what are bonds that have electrostatic forces between oppositely charged ions? (These are often metals with Nonmetals)

• covalet bond

• metallic bond

• Ionic bonds

• octet bond

What are some traits of ionic bonding?

• They share valence electrons, and they are an exception to the octet rule

• Formula starts with a metal, Electrolytes - conduct electricity in water, and soluble in water

• Can be solids, liquids, and gases, and they tend to glow in the dark

• polar bonds and liquids which means they tend to have a greater radii point

• Crystalline solids, strong bonds, and high melting points

What are bonds that share valence electrons (Nonmetals with nonmetals)?

Draw the following as indicated:

In a number line from 0 to 2, label Nonpolar, polar, and ionic bond using E.N. differences.

Answer explanation

Mrs. Hatter taught us this to memorize from 0-0.4 it is nonpolar, from .5 to 2 it is polar, and from 2 on it is an ionic bond

True or false: In metallic bonds, valence electrons move from atom to atom.

• True

• False

Draw partial negative/positive where needed.

use this molecule- B - Cl

Answer explanation

An ___ attraction exists between an ION and the partial charge on the end of a polar molecule (aka dipole).

• Ion- ion

• Ion - Dipole

• Dipole-Dipole

• None of the above

Ionic bonds have a ___ ___ that have a 3-d, repeated unit cell.

What rule states that atoms share, lose, or gain valence electrons to obtain eight valence electrons.

• Heisenberg Uncertainty Principle

• Bohr's Theory
• Quantum Theory
• Octet Rule

True or false: triple bonds share 6 e-s, and are the shortest and strongest bond out of the three bonds.

• True

• False
