Expert Answer:

 
  • Lithium and beryllium are the first elements of Group 1 and 2 respectively exhibit some properties which are different from those of the other members of the respective group.
  • They both show similarity in properties of the second element of the following group. 
  • That means, in these anomalous properties they resemble the second element of the following group.
  • Thus lithium shows similarities to magnesium and beryllium to aluminium in many of their properties.
  • This type of diagonal similarity is commonly referred to as Diagonal Relationship in the periodic table.
