Front

How many valence electrons does Lithium have in its Lewis dot model?

Back

1

Front

What are ions?

Back

Atoms with a positive or negative charge.

Front

What is the goal of the Lewis Dot Structure?

Back

To show the element's valence electrons & bonding capabilities.

Front

What is a positive ion called?

Back

Cation.

Front

Is this a correct dot diagram for nitrogen (N)?

Back

True.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is a negative ion called?

Back

Anion.

Front

How do you determine the charge of an ion?

Back

By comparing the number of protons and electrons in an atom.

Front

What is the significance of the octet rule?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

What does a Lewis dot diagram represent?

Back

The valence electrons of an atom and how they can bond with other atoms.
