Organic Chemistry- Atomic Orbitals

Organic Chemistry - Atomic Orbitals 
The element carbon is in row two of the periodic chart and has six electrons. This indicates that these electrons have access to two atomic orbital shells. The 1s orbital is the only s orbital in the first shell that is closest to the nucleus. Three p orbitals and one s orbital (the 2s orbital) make up the second shell (3 2p). These six electrons can therefore fit into a total of five atomic orbitals. The 2s orbital is significantly larger than the 1s orbital, and the s orbitals are spherical in shape. The x, y, and z axes are parallel to and in line with the dumbbell-shaped p orbitals. They are therefore given the atomic orbitals 2px, 2py, and 2pz.
