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 to achieve a more stable electron configuration.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is the formula for dichloride pentoxide?

Back

Cl2O5

Front

What is the correct formula for hydrobromic acid?

Back

HBr

Front

What is an exception to the octet rule?

Back

An exception to the octet rule can occur in molecules with an odd number of electrons, leading to unpaired electrons.

Front

What type of bond is formed when two pairs of electrons are shared?

Back

A double covalent bond.

Front

What type of bond is formed when three pairs of electrons are shared?

Back

A triple covalent bond.

Front

What is a single covalent bond?

Back

A single covalent bond is formed when two atoms share one pair of electrons.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where the electrons are shared unequally between the two atoms, resulting in a molecule with a slight charge.
