Questions based on paragraph Study the following activity and answer the questions. Take two aluminium channels of different lengths. Place the lower ends of the channels on the floor and hold their upper ends at the same height. Now take two balls of the same size and weight and release them from the top end of the channels. They will roll down and cover the same distance. Which law related to energy does the above activity demonstrate? Explain.

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
