Interpretation:
The missing period, group element and electronic configuration in the given table need to be identified.
Period | Group | Element | Electronic Configuration |
3 | Mg | [Ne] 3s2 | |
4 | 14 | Ge | |
12 | Cd | [Kr] 5s2 4d10 | |
2 | 1 | [He] 2s1 |
Concept introduction:
A periodic table consists of groups and periods. The horizontal rows are termed as periods and the vertical rows are termed as groups. The elements with similar properties are placed together in a group. The elements are also located according to their respective blocks like s, p, d or f block.

Answer to Problem 57A
Period | Group | Element | Electronic Configuration |
3 | 2 | Mg | [Ne] 3s2 |
4 | 14 | Ge | [Ar] 3d10 4s2 4p2 |
5 | 12 | Cd | [Kr] 5s2 4d10 |
2 | 1 | Li | [He] 2s1 |
Explanation of Solution
The electronic configuration of Magnesium is [Ne] 3s2 and contains two valence electrons so one can predict that Mg belongs to group 2.
Germanium is located in group 14 and period 4 having
Cadmium has electronic configuration [Kr] 5s2 4d10. Therefore, it is located in period 5.
From the electronic configuration [He] 2s1 one can say that the element is Lithium.
Thus, the complete table is as follows:
Period | Group | Element | Electronic Configuration |
3 | 2 | Mg | [Ne] 3s2 |
4 | 14 | Ge | [Ar] 3d10 4s2 4p2 |
5 | 12 | Cd | [Kr] 5s2 4d10 |
2 | 1 | Li | [He] 2s1 |

- (a) Show that the lattice energies are inversely proportional to the distance between ions in MX (M = alkali metal, X = halide ions) by plotting the lattice energies of KF, KCl, and KI against the internuclear distances, dMX. The lattice energies of KF, KCl, and KI are 826, 717, and 645 kJ/mol, respectively. Does the correlation obtained correlate well? You will need to use a standard graphing program to construct the graph (such as a spreadsheet program). It will generate an equation for the line and calculate a correlation coefficient. (b) Estimate the lattice energy of KBr from your graph. (c) Find an experimental value for the lattice energy of KBr in the literature, and compare this value with the one calculated in (b).
