Li resembles Mg this is called diagonal relationship which is attributed to

Which elements in the periodic table show a diagonal relationship ?

The similarity between Li to group 1 and Mg of group 2 is called a diagonal relation. It arises because

In the modern periodic table, the elements are arranged in the increasing order of their atomic number. This arrangement is based on the modern periodic law, which states that the properties of elements are a periodic function of their atomic numbers. In the modern periodic table, each column is called a group and each row is called a period. Elements within the same group show similarity and gradation in properties. This is due to the same number of electroms in the outermost shell . Based on the above paragraph, answer the following question: Which pair of elements do you think will have similar properties? a. Sodium and Argon b. Sodium and Potassium c. Potassium and Neon
