Which of the metals are usually referred to as lighter metals?A. `f`-block metalsB. `d`-block metalsC. `p`-block metalsD. `s`-block metals |
|
Answer» Correct Answer - D By definition, lighter metals have densities less than `5 g cm^(-3)`. All `s-`block metals except `Ra(5.5g cm^(-3))` have densities less than `5gm cm^(-3)`. In `d-`block metals, only `Sc(3.0g cm^(-3)), Ti(4.5 g cm^(-3))`, and `(4.5g cm^(-3))` have densities less than `5 g cm^(-3)`. |
