Answer the equation based on the given data Arrange the above elements in an increasing order of atomic radii.Does this arrangement match with the pattern of the group in the above answer?

Answer the following questions: What is the periodic trend in the variation of valency while going down a group? Explain your answer with refrence to the group 1, group 2 and group 18.

Answer the equation based on the given data To which group do the elements belong?What is the family called ?

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: What is the trend in the variation of valency while going down a group?

What would be the expected trend in the variation of non-metallic character of elements down a group?

Answer the following based on the graph given below. What is the frequency of AC and DC?
