Unit6 Practice Flashcard1

Front

What type of bond has an equal sharing of electrons?

Back

Non Polar Covalent

Front

What are the typical electronegativity values for metals and nonmetals?

Back

Metals tend to have low electronegativity values and nonmetals tend to have high electronegativity values.

Front

What occurs during the formation of an ionic bond?

Back

Atoms transfer electrons.

Front

What type of bonding is present in Strontium Fluoride?

Back

Ionic due to a high ΔEneg value.

Front

What factors influence the strength of the effect of the nucleus on outer level electrons?

Back

The distance of the nucleus from the outer level and the charge of the nucleus (Z).

Front

Define electronegativity.

Back

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

Front

What is a polar covalent bond?

Back

A bond where electrons are shared unequally between atoms, resulting in partial charges.

Front

What is an ionic bond?

Back

A bond formed through the transfer of electrons from one atom to another, resulting in charged ions.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds have unequal sharing of electrons, while nonpolar covalent bonds have equal sharing.

Front

What is the significance of ΔEneg in determining bond type?

Back

ΔEneg indicates the difference in electronegativity between two atoms, helping to classify the bond as ionic, polar covalent, or nonpolar covalent.
