What is the role of valence electrons in ionic bonding?

• Valence electrons are involved in the transfer between atoms to form ions.

• Valence electrons are responsible for the color of the ions.

• Valence electrons determine the mass of the ions.

• Valence electrons are not involved in ionic bonding.

How do you determine the formula of an ionic compound?

• By balancing the total positive and negative charges.

• By using the atomic mass of the elements involved.
