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 a lone pair?

Back

A lone pair is a pair of non-bonding electrons.

Front

What is a valence electron?

Back

A valence electron is an electron found in the outermost shell of an atom.

Front

What do covalent compounds do?

Back

Covalent compounds share electrons.

Front

What is the Lewis Dot Structure used for?

Back

The Lewis Dot Structure is used to represent the valence electrons of atoms and how they bond with each other.

Front

What is the significance of lone pairs in Lewis Dot Structures?

Back

Lone pairs can affect the shape and reactivity of molecules.

Front

What is the general rule for drawing Lewis Dot Structures?

Back

The general rule is to count the total number of valence electrons and distribute them to satisfy the octet rule.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell.
