Alkali metals (Group 1 elements in the periodic table) are known to be very reactive. Which statement accurately explains the reactivity of the alkali metals?
A. Alkali metals have very low density, which makes them very reactive, because they want to gain energy and become stable.
B. Alkali metals are in Group 1 of the periodic table making them less reactive because the reactivity of a metal increases from left to right across each row.
С. Alkali metals are very reactive because they all are solids at room temperature.
D. Alkali metals are all in Group 1 of the periodic table making them very reactive because the reactivity of a metal increases from right to left across each row.​

The statement that accurately explains the reactivity of the alkali metals is A. Alkali metals have very low density, which makes them very reactive, because they want to gain energy and become stable.

Alkali metals are elements in group 1 and they include Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs) and Francium (Fr).

  • They have low densities
  • They are very reactive since they have one electron in their valence shell and want to achieve the stable octet configuration of the noble gases.

So, the statement that accurately explains the reactivity of the alkali metals is A. Alkali metals have very low density, which makes them very reactive, because they want to gain energy and become stable.
