Polarity

Question 1

A chemical bond where one atom donates electrons to another atom.

Answer 1

Ionic Bond

Question 2

Typically occurs between atoms with significantly different electronegativities.

Answer 2

Ionic Bond

Question 3

Forms positively- and negatively-charged ions.

Answer 3

Ionic Bond

Question 4

An atom or group of atoms that has an electric charge.

Answer 4

Ion

Question 5

A chemical bond where atoms share valence electrons to become stable.

Can either be polar or non-polar.

Answer 5

Covalent Bond

Question 6

Outermost shell of the atom.

Answer 6

Valence Electrons

Question 7

These can be shared/donated during chemical bonds. These also determine the polarity of the bond.

Answer 7

Valence Electrons

Question 8

Electrons of atoms that are shared unevenly.

Answer 8

Polar Bond

Question 9

Electrons of atoms that are shared evenly.

Answer 9

Non-polar Bond

Question 10

Formed when different elements bond.

Answer 10

Compounds

Question 11

There are 2 ways to identify the Polarity of a Compound. These are…

Answer 11

• Based on Electronegativity Difference
