Molecular Structure

Molecular Structure. Both atoms and molecules are quantum systems We need a method of describing molecules in a quantum mechanical way so that we can predict structure and properties The method we use is the Linear Combination of Atomic Orbitals

When you gain an electron, you gain a positive charge

Electrons in outermost shell are called valence electrons and the valence shell is the outermost occupied shell Electron Configuration of Ions CATIONS are formed when a neutral atom loses one or more electrons: np electrons are lost first ns electrons are lost second
