Which among the following statement is NOT true?
Options
- ACompounds of unipositive ions of alkali metals are paramagnetic.
- BAlkali metals have low density.
- CAll alkali metals are silvery white and soft.
- DAlkali metals are most electropositive elements.
Correct answer
A. Compounds of unipositive ions of alkali metals are paramagnetic.
Step-by-step solution
Alkali metals are soft and can be cut by knife. Alkali metals have low density-Lithium, sodium and potassium float on water. They have low ionization energies and their atoms readily lose the valence electron hence they are most electropositive elements. Alkali metal salts are diamagnetic.
