Li resembles Mg due to diagonal relationship, which is attributed to :
A
Similar atomic and ionic size
B
Similar electronegativity
C
Similar ionization enthalpy
D
Both (1) and (2)
Answer
Both (1) and (2)
Explanation
Solution
On descending a group, the atoms and ions increase in size. On moving from left to right the size decreases. Thus on moving diagonally the size remains nearly the same. They also have nearly same IE & EN values.
