Element Lewis Dot and Ion Formation

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 in the molecule.

Front

How many valence electrons does fluorine (F) have?

Back

Fluorine has 7 valence electrons.

Front

What ion does fluorine typically form when it gains an electron?

Back

Fluorine typically forms a 1- ion when it gains an electron.

Front

What is the general rule for determining the charge of an ion formed by nonmetals?

Back

Nonmetals typically gain electrons to achieve a full outer shell, resulting in a negative charge.

Front

What is the charge of a sodium ion (Na) when it loses an electron?

Back

The charge of a sodium ion (Na) when it loses an electron is 1+.

Front

What is the significance of valence electrons in ion formation?

Back

Valence electrons are the electrons in the outermost shell of an atom and are involved in forming bonds and ions.

Front

How many energy levels does an element with 7 valence electrons have?

Back

An element with 7 valence electrons can have multiple energy levels; the specific number depends on the element.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

What type of ion does a metal typically form?

Back

A metal typically forms a positive ion (cation) by losing one or more electrons.

Front

What is the electron configuration of fluorine?

Back

The electron configuration of fluorine is 1s² 2s² 2p⁵.
