1 Sp08 ECE331 Homework #1 Solution 1. The n quantum number designates the electron shell. The l quantum number designates the electron subshell. The m l quantum number designates the number of electron states in each electron subshell. The m s quantum number designates the spin moment on each electron. 2. The Na+ ion is just a sodium atom that has lost one electron; therefore, it has an electron configuration the same as neon (Figure 2.6). The Cl- ion is a chlorine atom that has acquired one extra electron; therefore, it has an electron configuration the same as argon. 3. (a) Curves of E A , E R , and E N are shown on the plot below. (b) From this plot r o = 0.24 nm E o = -5.3 eV

2 4. For silicon, having the valence electron structure 3s 2 3p 2 , N' = 4; thus, there are 8 - N' = 4 covalent bonds per atom. For bromine, having the valence electron structure 4s 2 4p 5 , N' = 7; thus, there is 8 - N' = 1 covalent bond per atom. For nitrogen, having the valence electron structure 2s
