What is the symbol of the element in Group 4A(14) and Period 2?

In the periodic table, calcium, element 20, is surrounded by elements 12 magnesium , 19 potassium, 21 scandium, and 38 strontium. Which of these have physical and chemical properties most resembling calcium?

5 g of anhydrous strontium nitrate is added to a beaker and exposed to the air. After several hours the beaker and the contents are weighed. It was found that the mass increased by 1.70 g. Assume that the increase in mass is totally due to the absorption of water by the anhydrous compound. What is the percentage of water in the hydrated sample?
