Worksheet 9.1: Bond Types

Front

What type of bond is formed by the transfer of electrons?

Back

Ionic bond is formed when electrons are transferred from one atom to another, resulting in the formation of charged ions.

Front

If ΔEN is between 0.4 and 1.7, what type of bond is likely formed?

Back

Polar Covalent bond is likely formed when the difference in electronegativity (ΔEN) between two atoms is between 0.4 and 1.7.

Front

Which molecule is an example of a polar covalent molecule?

Back

Water (H₂O) is a polar covalent molecule due to the unequal sharing of electrons between hydrogen and oxygen.

Front

What type of bond results in delocalized electrons that move freely?

Back

Metallic bond results in delocalized electrons that can move freely, allowing for conductivity and malleability.

Front

Which substance has the strongest bond strength?

Back

Sodium Chloride (NaCl) has the strongest bond strength among the given options due to its ionic nature.

Front

Define a covalent bond.

Back

A covalent bond is formed when two atoms share one or more pairs of electrons.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs between two atoms when one atom donates an electron to another, resulting in the attraction between oppositely charged ions.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

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

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

What is a metallic bond?

Back

A metallic bond is a type of bond formed by the attraction between positively charged metal ions and the delocalized electrons surrounding them.
