Valence Electrons

Front

What are valence electrons?

Back

Valence electrons are electrons that are found in the outermost shell of an atom.

Front

How many valence electrons do elements in the same group of the periodic table have?

Back

Elements in the same group of the periodic table have the same number of valence electrons.

Front

How many valence electrons does Nitrogen have?

Back

Nitrogen has 5 valence electrons.

Front

Which group in the periodic table has the greatest number of valence electrons?

Back

Group 18 has the greatest number of valence electrons.

Front

What is the significance of valence electrons in chemical bonding?

Back

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

Front

What is the Lewis Dot Structure?

Back

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

Front

How many valence electrons does Carbon have?

Back

Carbon has 4 valence electrons.

Front

What happens to the reactivity of elements as you move down a group in the periodic table?

Back

Reactivity generally increases for metals and decreases for nonmetals as you move down a group.

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.

Front

What is the difference between core electrons and valence electrons?

Back

Core electrons are those in the inner shells, while valence electrons are in the outermost shell.
