Study the list of elements given below: Li, Mg, Si, Be, B, C, Al
Make three pairs of elements such that they show similarity in their properties.

Study the list of elements given below: Na, Mg, Li, B, C Select the pairs showing diagonal relationship.

Study the list of elements given below: Na, Mg, Si, Be, B, C, Al Discuss the concept based on which you selected the element pairs.

Account for the following: 'Li' and 'Mg' show similar properties

Here certain pairs of element are given. Which of the two have almost similar size?

Some d- block elements are given below. Cr, Mn, Fe, Co, Ni:- Identify The element which shows maximum paramagnetic behaviour.

2. Some d - block elements are given below: (Cr,Mn,Fe,Cos,Ni) a. Identify the element which shows maximum paramagnetic behaviour: b. Give reason for the highest paramagnetic property of that element. c. When two electrons, are Iost from each atom, is there any change:in' magnetic properties of - each. Explain?
