Inv. 3 Exp. 3 Covalent Bonding Practice

Front

Is Cl2 ionic or covalent?

Back

Covalent

Front

What is the correct Lewis Dot Structure for ammonia (NH3)?

Back

The Lewis Dot Structure for NH3 shows nitrogen in the center with three hydrogen atoms bonded to it, and a lone pair of electrons on nitrogen.

Front

Is SO2 ionic or covalent?

Back

Covalent

Front

Covalent bonds form between:

Back

Two nonmetals.

Front

How many valence electrons are most stable for an element in a compound (except hydrogen)?

Back

8

Front

What type of bond is formed between two nonmetals?

Back

Covalent bond.

Front

What is a Lewis Dot Structure?

Back

A diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

What is the octet rule?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

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 type of covalent bond where the electrons are not shared equally between the two atoms, resulting in a slight charge difference.
