Valence Electron Practice

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

What is the maximum number of electrons that the first orbital can hold?

Back

The first orbital can hold a maximum of 2 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 formation of molecules.

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

How do you determine the number of valence electrons using the periodic table?

Back

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