Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

What type of bond is formed when the difference in electronegativity is between 0.0 and 0.4?

Back

Nonpolar Covalent Bond.

Front

What type of bond is formed when the difference in electronegativity is between 0.5 and 1.7?

Back

Polar Covalent Bond.

Front

What type of bond is formed when the difference in electronegativity is greater than 1.7?

Back

Ionic Bond.

Front

What are Group 18 elements known as?

Back

Noble gases.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

Which element forms a covalent bond with Oxygen?

Back

Nitrogen.

Front

If an element has 3 valence electrons, what charge will its ion likely have?

Back

+3.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full set of eight valence electrons.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.
