Covalent Bonds Mod 7

Front

What is a covalent bond?

Back

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

Front

What is the molecular formula for water?

Back

H₂O, which consists of two hydrogen atoms and one oxygen atom.

Front

What is the shape of a water molecule?

Back

The shape of a water molecule is bent due to the two lone pairs of electrons on the oxygen atom.

Front

What is the bond angle in a water molecule?

Back

The bond angle in a water molecule is approximately 104.5 degrees.

Front

What is the difference between polar and non-polar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally between atoms, while non-polar covalent bonds occur when electrons are shared equally.

Front

What is the significance of bond length in covalent bonds?

Back

The bond length is the distance between the nuclei of two bonded atoms; longer bond lengths generally indicate weaker bonds.

Front

What is hydrobromic acid's chemical formula?

Back

HBr.

Front

What type of bond is formed between two nonmetals?

Back

A covalent bond.

Front

What is the molecular shape of H₂S?

Back

The molecular shape of H₂S is bent.

Front

What is a diatomic molecule?

Back

A diatomic molecule is a molecule composed of only two atoms, which can be of the same or different elements.
