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

The chemistry of lithium is very similar to that of magnesium even though they are placed in different groups because of diagonal relationship. So, the ratio of their charge and size (i.e. charge density) is nearly the same
