What is the significance of valence electrons in chemical reactions?

Back

Valence electrons determine how an atom can bond with other atoms and influence the chemical properties of the element.

Front

Will Phosphorus tend to gain or lose electrons?

Back

Phosphorus will tend to gain electrons.

Front

What is the maximum number of valence electrons an atom can have?

Back

The maximum number of valence electrons an atom can have is 8, following the octet rule.

Front

Which group of the periodic table has the highest number of valence electrons?

Back

Group 18 (Noble gases) has the highest number of valence electrons, which is 8, except for Helium which has 2.

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.
