Lewis structures

Front

What is a covalent bond?

Back

A bond that shares electrons between non-metals.

Front

When drawing Lewis structures, which electrons are used?

Back

Valence electrons.

Front

How many total valence electrons are participating in bonding in a typical molecule?

Back

8.

Front

How many electrons are shared in each bonding line in a Lewis structure?

Back

2.

Front

How many electrons does hydrogen need in its outer energy level to be stable?

Back

2.

Front

What are Lewis structures used for?

Back

To represent the bonding between atoms in a molecule and the lone pairs of electrons.

Front

What is the octet rule?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell.

Front

What is a lone pair in a Lewis structure?

Back

A pair of valence electrons that are not shared with another atom.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are involved in forming bonds between atoms.

Front

What does it mean for an atom to be stable?

Back

An atom is stable when its outer electron shell is full.
