Electronegativity and Bond Types

Front

What is Electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It is a key factor in determining the type of bond that will form between atoms.

Front

What type of bond is formed when electrons are shared equally between two atoms?

Back

Nonpolar Covalent Bond.

Front

What type of bond is formed when electrons are shared unequally between two atoms?

Back

Polar Covalent Bond.

Front

What type of bond is formed when one atom completely transfers electrons to another atom?

Back

Ionic Bond.

Front

Which element is more electronegative: Oxygen (O) or Beryllium (Be)?

Back

Oxygen (O) is more electronegative.

Front

What is the electronegativity difference that typically indicates a Polar Covalent Bond?

Back

An electronegativity difference of 0.1 to 1.7 indicates a Polar Covalent Bond.

Front

What is the electronegativity difference that typically indicates an Ionic Bond?

Back

An electronegativity difference greater than 1.7 indicates an Ionic Bond.

Front

What is the electronegativity difference that typically indicates a Nonpolar Covalent Bond?

Back

An electronegativity difference of 0 indicates a Nonpolar Covalent Bond.

Front

In a Polar Covalent Bond, what do the partial charges on the atoms indicate?

Back

The partial charges indicate that one atom has a stronger attraction for the shared electrons than the other, leading to unequal sharing.

Front

What is an example of a molecule with a Nonpolar Covalent Bond?

Back

An example is a molecule of Hydrogen (H2), where two Hydrogen atoms share electrons equally.
