🍟 6.1 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 does Aluminum have?

Back

Aluminum has 3 valence 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 bonds can an atom with 4 valence electrons typically form?

Back

An atom with 4 valence electrons can typically form 4 bonds.

Front

What happens to an atom when it gains an electron?

Back

When an atom gains an electron, it becomes negatively charged and is called an anion.

Front

What happens to an atom when it loses an electron?

Back

When an atom loses an electron, it becomes positively charged and is called a cation.

Front

Which group of elements has a full valence shell?

Back

Noble gases have a full valence shell, typically with 8 valence electrons.

Front

What is the significance of valence electrons in chemical reactions?

Back

Valence electrons determine how an atom will bond with other atoms, influencing the type of chemical reactions it can undergo.

Front

What is the maximum number of electrons that can occupy the outermost shell of an atom?

Back

The maximum number of electrons that can occupy the outermost shell is 8, according to the octet rule.
