1.	Name the two elements that would expect to have chemical properties similar to element with atomic number 11. What is the base for your choice?
Answer» 1. The element with atomic number 11 is sodium and its electronic configuration is 1s² 2s² 2p⁶ 3s¹or 2, 8, 1. 2. So it has one valence electron, i.e. present in I group. We know that the elements present in same group have same valence electrons. So they show similar properties. 3. Therefore the other two elements are Lithium and Potassium.
