Diagonal similarities in the Periodic Table

Give some illustrations of diagonal similarities in the periodic table, and explain each. 

Nitrogen and sulfur are diagonally related in the periodic table and might therefore be expected to have similar electronic charge densities for... 

Diagonal relationships in the periodic table exist as well as the vertical relationships. For example, Be and Al are similar in some of their properties, as are B and Si. Rationalize why these diagonal relationships hold for properties such as size, ionization energy, and electron affinity. 

Diagonal neighbors in the periodic table have similar polarizability values and a similar amount of covalent character in the bonds they form. 

Be and A1 are diagonal neighbors in the periodic table and exhibit similar chemical behavior. 

Figure 14.2 Three diagonal relationships in the periodic table. Certain Perbd 2 elements exhibit behaviors that are very similar to those of the Period 3 elements immediately below and to the right. Three such diagonal relationships exist Li and Mg, Be and Al, and B and Si.

Alkaline earth metals are involved in two key diagonal relationships in the periodic table, (a) Give the two pairs of elements in these diagonal relationships, (b) For each pair, cite two similarities that demonstrate the relationship, (c) Why are the members of each pair so similar in behavior ... 

The linear relationship analysis results of heavy metals and the coefficient matrix are shown in Table 3.37, Cu-Cd and As-Cd showed a strong correlation. Cu and Cd take a diagonal position in the periodic table, and thus their chemical properties are similar and have comparable controlling factors. They displayed similar high content areas in the south of the Shandong Peninsula and in central SYS clay area, and their low content area in China s inshore area As and Cd showed a strong negative linear correlation, because As was a... 

Intermetallic chemistry of Be, Mg, Zn, Cd and Hg 5.12.4.1 Phase diagrams of the Be, Mg, Zn, Cd and Hg alloys. The systematics of the compound formation of these metals in their binary alloys with the different elements is summarized in Fig. 5.33. On the overall they give a rather complex picture even so a number of relationships and similarities between various pairs of metals may be singled out. To go into this point in more detail, in the same figure a comparison has also been made with the compound formation patterns of Ca and A1 which are described in 5.4 and 5.13 but are close in the Periodic Table to the metals here considered. The similarity between the Be and Zn patterns may be underlined, as also that between Be and Al, being an example of the so-called diagonal relationships presented in 4.2.2.2. 

A diagonal relationship is a similarity in chemical properties between an element in the periodic table and one lying one period lower and one group to the right.
