Give the name of the compound Li₂O

Lithium Oxide

200

Give the formula of the compound Potassium Fluoride

300

Explain in detail how an ionic bond is formed

Ionic Bonds are formed through transferred electrons. The metal atom gives it's valence electrons to the nonmetal atom.

400

Oppositely charged ions attract each other, forming what kind of bond?

Ionic Bond

500

What two things are produced through the transferring of electrons?

Salts & Crystals

Covalent Bonds

100

Why do atoms share electrons in covalent bonds?

To attain a noble-gas electron configuration

200

How do atoms achieve noble-gas electron configurations in single covalent bonds?

  A. two atoms share two electrons

  B. two atoms share two pairs of electrons

  C. two atoms share one electron

  D. One atom completely loses two electrons to the other atom in the bond.

A. Two atoms share two electrons

Molecular Structures

100

TRUE or FALSE: Tetrahedral shaped molecules have three electron pairs bonded to a central atom.

False, tetrahedral shaped molecules have FOUR electron pairs bonded to a central atom.

200

What is the molecular structure and bond angle of water?

Bent/Angular & 104.4 degrees

300

What does VSEPR stand for?

Valence Shell Electron Pair Repulsion

400

Explain the difference between the electron-pair geometry shape & the molecular structure shape

EPG shows the shape with all types of electron pairs & MS shows the shape with only the bonding pairs of electrons

500

Give the EPG shape & the molecular shape of the molecule Hydrogen Fluoride (HF).

EPG = Tetrahedral

Molecular Structure = Linear 

Valence Electrons

100

What is one way to determine the number of valence electrons an atom has?

Group/family number

+2

300

How many electrons are shared in a triple covalent bond?

6

400

Explain in detail how a covalent bond is formed.

Covalent bonds are formed when two nonmetals share valence electrons with one another to complete each atoms outer shell.
