Ionic Bonding and Valence Electrons

Study Notes

Ionic Bonding and Valence Electrons

Phosphorus forms an ion with a charge of 3- (P3-) by gaining three electrons to achieve a stable set of valence electrons.
Ionic bonds involve the transfer of electrons, where metal atoms lose electrons, and nonmetal atoms gain them.

Electron Transfer in Ionic Bonds

Metals, due to low electron affinities, easily lose their valence electrons and turn into positively charged ions.
Nonmetals have high electron affinities and gain electrons, resulting in negatively charged ions.
The electrostatic attraction between positively charged metal ions and negatively charged nonmetal ions results in the formation of ionic bonds.

Ionic Bond Construction Example

In forming an ionic bond between beryllium (Be) and chlorine (Cl), it's necessary to add another chlorine atom after the first electron transfer to stabilize the beryllium’s single valence electron.
The final chemical formula for the compound formed is BeCl2.

Zinc Phosphide and Valence Electrons

Zinc phosphide (Zn3P2) requires each zinc atom to lose 2 valence electrons to provide phosphorus with the needed 3 electrons for stability, as phosphorus has 5 valence electrons.

Rubidium Nitride and Chemical Families

Rubidium, being in the same chemical family as lithium, shares similar valence electron properties.
The formula for rubidium nitride is Rb3N, paralleling the formula for lithium nitride (Li3N).
