Valence Electrons, Bohr Model, Lewis Structure

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

How many valence electrons does Chlorine (Cl) have?

Back

Chlorine has 7 valence electrons.

Front

What is the Bohr Model?

Back

The Bohr Model is a simplified representation of an atom that shows electrons in specific energy levels around the nucleus.

Front

What do electrons live in?

Back

Electrons live in shells or energy levels.

Front

How many electrons can fit in the first energy level?

Back

The first energy level can hold 2 electrons.

Front

How many electrons can fit in the second energy level?

Back

The second energy level can hold 8 electrons.

Front

What is a Lewis dot structure?

Back

A 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 (N) have?

Back

Nitrogen has 5 valence electrons.

Front

What is the maximum number of electrons in the third energy level?

Back

The third energy level can hold up to 18 electrons.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms to form molecules.
