Covalent Bonds Review

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 the Octet Rule?

Back

The Octet Rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, which is considered a stable configuration.

How many valence electrons does oxygen have?

Back

Oxygen has 6 valence electrons.

Front

What is the difference between a single, double, and triple covalent bond?

Back

A single covalent bond involves one pair of shared electrons, a double bond involves two pairs, and a triple bond involves three pairs.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Front

What is a Lewis dot structure?

Back

A Lewis dot structure is a diagram that represents the valence electrons of an atom as dots around the element's symbol.

Front

What is resonance in chemistry?

Back

Resonance refers to the phenomenon where a molecule can be represented by two or more valid Lewis structures that differ only in the placement of electrons.

Front

What is the significance of the shared electron pairs in covalent bonds?

Back

Shared electron pairs in covalent bonds allow atoms to achieve a full outer shell, leading to greater stability.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where the electrons are shared unequally between two atoms, resulting in a partial positive and negative charge.
