Atomic Structure, Periodicity, and Bonding

Atomic Structure, Periodicity, and Bonding. Sizes of Ions. Ionic size depends upon: The nuclear charge. The number of electrons. The orbitals in which electrons reside. Sizes of Ions. Cations are smaller than their parent atoms.

Quantum Numbers ? n,l,ml :

Quantum Numbers ? n,l,ml :. n = 1 ? l = 0 ? l = 0 therefore ml = 0 Giving ? 1s or ? 1,0,0 or 1s orbital. n = 1 has 1 orbital. n = 2 ? l = 0, 1? l = 0 therefore ml = 0 Giving ? 2s or ? 2,0,0 or 2s orbital l = 1 therefore ml = -1,0,1 Giving ? 2,1,0 or 2p z orbital

Overlap and Bonding

Overlap and Bonding. We think of covalent bonds forming through the sharing of electrons by adjacent atoms. In such an approach this can only occur when orbitals on the two atoms overlap. Overlap and Bonding.
