Now, about the types of orbitals and their relative energy levels. There are four types of atomic orbitals – s, p, d, and f. Each orbital has a characteristic shape shown below: S orbitals have a spherical shape, p orbitals are dumbbell -shaped, d orbitals are shaped like a cloverleaf, and f orbitals are characterized by more complex shapes.

P-chem. These are arbitrarily given the symbols px, py and pz. This is simply for convenience; the x, y, and z directions change constantly as the atom tumbles in space. Figure 3: Hydrogen's electron - the 2p orbitals. The p orbitals at the second energy level are called 2p x, 2p y and 2p z. There are similar orbitals at subsequent levels: 3p x, 3p y ...

The labels s, p, d and f blocks of the Periodic Table refer to the subshell that is being filled with electrons. ⚛ Group 1 elements occur at the beginning of a new row (Period) of the Periodic Table. The highest energy level (valence shell) contains only 1 electron in an s subshell. ⚛ Group 2 elements occur directly to the right of Group 1 ...
