On this basis, how many atoms are there in a pound-mole of a substance?
Solution a Two important quantum-mechanical concepts associated with the Bohr model of the atom are 1 that electrons are particles moving in discrete orbitals, and 2 electron energy is quantized into shells. Solution The n quantum number designates the electron shell. The l quantum number designates the electron subshell. The ml quantum number designates the number of electron states in each electron subshell.
The ms quantum number designates the spin moment on each electron. Write the four quantum numbers for all of the electrons in the L and M shells, and note which correspond to the s, p, and d subshells. Therefore, for the s states, the quantum numbers are 2 2 1 1 1 1 1 1.
For the p states, the quantum numbers are , - , , - , 21 -1 , and 2 2 2 2 2 2 1. Solution The electron configurations for the ions are determined using Table 2.
In order to become an ion with a plus five charge, it must lose five electrons—in this case the three 3p and the two 3s. Rowland, A. Sironi, G. Microwave plasma detectors A. The sulfur chemiluminescence detector R.

Polarization of ions Fajans' rules state that polarization is enhanced by High charge and small size of the cation High charge and large size of the anion Cations with 18 electron structures e.
Discussion of Fajans' Rules Ionic compounds traditionally have the following properties. Hard and brittle with high melting points Conduct electricity in solution Dissolve in polar solvents High temperature electrolysis Polarization in an ionic bond will lead to covalency and hence deviate from the above properties.
Let's look at specific examples and discuss. We can rationalize this trend by Fajans' rules.
In these three compounds, bromide is the common anion. According to Fajans' rules, higher charge leads to polarization and hence increased covalency in a molecule.
So covalency is highest in AlBr3 and least in NaBr.
