Question

The chemistry of lithium is very similar to that of magnesium even though they are placed in different groups. Its reason is

• A. Both are found together in nature
• B. Both have nearly the same size
• C. Both have similar electronic configuration
• D. The ratio of their charge and size (i.e charge density) is nearly the same

Answer 1

The correct option is D The ratio of their charge and size (i.e charge density) is nearly the same

Due to diagonal relationship Li and Mg show similarities.
