Solid State Electronic Devices, 7th Edition

The top table has 3 rows, corresponding to value of n, value of l, and state of electrons. Column 1, n equals 1, l equals 0, electron state equals 1 s. Column 2, n equals 2, l equals 0, 2.s. Column 3, n equals 2, l equals 1, 2p. Column 4, n equals 3, l equals zero, 3 s. Column 5, n equals 3, l equals 1, 3 p. Column 6, n equals 3, l equals 2, 3 d. Column 7, n equals 4, l equals 0, 4 s. Column 8, n equals 4, l equals 1, 4 p. The bottom table has 6 columns, from left to right, atomic number, Z, Element, number of electrons in 1 s, number of electrons in 2 s, number of electrons in 2 p, number of electrons in 3 s, number of electrons in 3 p, number of electrons in 3 d, number of electrons in 4 s, number of electrons in 4 p, shorthand notation.
