Lewis Dot Structure

Front

What are valence electrons?

Back

The outermost electrons of an atom that are involved in chemical bonding.

Front

What is the correct dot diagram for oxygen (O)?

Back

The correct dot diagram for oxygen shows 6 valence electrons, not 8.

Front

What is the correct dot diagram for sodium (Na)?

Back

The correct dot diagram for sodium shows 1 valence electron.

Front

What is electron dot notation?

Back

A representation of an element in which only the valence electrons of an atom are shown.

Front

How many electrons should Helium have around its Lewis dot model?

Back

Helium should have 2 electrons around its Lewis dot model.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons determine how an atom can bond with other atoms.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons can be determined from the group number in the periodic table.

Front

What does a Lewis dot structure represent?

Back

A Lewis dot structure represents the arrangement of valence electrons around an atom.

Front

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

Back

The maximum number of electrons in the outer shell is 8, following the octet rule.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have 8 electrons in their valence shell.
