Valence Electrons and Lewis Dot Structures

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have eight valence electrons, achieving a stable electron configuration.

Front

What are valence electrons?

Back

Valence electrons are the electrons located in the outermost shell of an atom, which are involved in chemical bonding.

Front

How many valence electrons do most elements aim to have?

Back

Most elements aim to have 8 valence electrons.

Front

What is the maximum number of electrons that the first shell can hold?

Back

The first shell can hold a maximum of 2 electrons.

Front

Which element has a full valence shell?

Back

Neon has a full valence shell.

Front

What happens to elements with fewer than 4 valence electrons?

Back

Elements with fewer than 4 valence electrons tend to lose electrons to achieve a stable configuration.

Front

What happens to elements with more than 4 valence electrons?

Back

Elements with more than 4 valence electrons tend to gain electrons to achieve a stable configuration.

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 do you represent valence electrons in a Lewis dot structure?

Back

Valence electrons are represented as dots around the chemical symbol of the element.

Front

What is the significance of a full valence shell?

Back

A full valence shell indicates that an atom is stable and less likely to react chemically.
