Lewis Structures

Front

What are Lewis Structures?

Back

Lewis Structures are diagrams that represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

How many valence electrons does Lithium have?

Back

Lithium has 1 valence electron.

Front

What type of ions do metals typically form?

Back

Metals typically form positive ions.

Front

How does an atom of aluminum become an ion?

Back

An atom of aluminum becomes an ion by losing 3 electrons.

Front

Which element is most likely to gain electrons in a chemical reaction?

Back

Bromine (Br) is most likely to gain electrons.

Front

What is a valence electron?

Back

A valence electron is an electron that is found in the outermost shell of an atom and can participate in forming chemical bonds.

Front

How many valence electrons does Magnesium have?

Back

Magnesium has 2 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, influencing the molecule's structure and properties.

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, achieving a stable electron configuration.

Front

How do you represent a lone pair of electrons in a Lewis Structure?

Back

A lone pair of electrons is represented by two dots placed next to each other.
