# Which properties would NOT be associated with the alkali metals? "A. High densities." "B. Low atomic masses." "C. Lustre." "D. Reactivity with water."

$\text{Option A........}$
$\text{Option A,}$ high densities are NOT properties associated with the alkali metals. Lithium, sodium, and potassium, would float on water (but for the reason that these metals react with water).
