Covalent Bonding

Front

What is a covalent bond?

Back

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

Front

What types of atoms typically form covalent bonds?

Back

Covalent bonds are typically formed between two non-metal atoms.

Front

What is the Lewis Dot Structure?

Back

The Lewis Dot Structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

How many valence electrons does nitrogen have?

Back

Nitrogen has 5 valence electrons.

Front

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

Back

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

Front

What is the significance of shared electrons in covalent bonding?

Back

Shared electrons allow atoms to achieve a full outer shell, leading to greater stability.

Front

What does a double bond represent in terms of electron sharing?

Back

A double bond represents the sharing of two pairs of electrons between two atoms.

Front

How many single bonds are present in a molecule with three hydrogen atoms bonded to a central atom?

Back

There are 3 single bonds in a molecule like ammonia (NH3).

Front

What is the difference between a single bond and a double bond?

Back

A single bond involves one pair of shared electrons, while a double bond involves two pairs of shared electrons.
