How do atoms achieve a full valence shell during chemical bonding?

Multiple Choice

Why is stability important for atoms in chemical bonding?

• It allows atoms to have a full valence shell, making them less reactive.

• It makes atoms more reactive and changes their properties.

• It causes atoms to lose their identity, and become a molecule.

• It increases the number of electrons in all atoms.

Multiple Choice

Which type of ions are formed when metals lose electrons in an ionic bond?

• Cations

• Anions

• Neutrons

• Isotopes

Multiple Select

Select all statements that correctly describe the formation of ionic bonds.

• Electrons are transferred from metals to nonmetals.

• Both atoms share electrons equally.

• A positive ion and a negative ion attract each other.

• Metals gain electrons to become cations.
