Electronegativity and Covalent Bonds

Front

What is Electronegativity?

Back

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

Front

What is a Covalent Bond?

Back

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

Front

What is an Ionic Bond?

Back

An ionic bond is a type of chemical bond that involves the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What is a Polar Covalent Bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms, leading to a slight charge difference.

Front

How does electronegativity affect bond type?

Back

The difference in electronegativity between two atoms determines whether the bond formed is covalent, polar covalent, or ionic.

Front

What is the electronegativity difference for a nonpolar covalent bond?

Back

The electronegativity difference for a nonpolar covalent bond is typically 0.

Front

What is the electronegativity difference for a polar covalent bond?

Back

The electronegativity difference for a polar covalent bond is usually between 0.1 and 1.7.

Front

What is the electronegativity difference for an ionic bond?

Back

The electronegativity difference for an ionic bond is generally greater than 1.7.

Front

What is the significance of the prefix 'tetra-' in chemical nomenclature?

Back

The prefix 'tetra-' indicates that there are four atoms of a particular element in a compound.

Front

What is the name of the compound B4C?

Back

The compound B4C is named tetraboron monocarbide.
