The element must be an Alkali-earth metal

Explanation:

The elemental properties given above is for the alkali-earth metals.

Member of the group are:

Magnesium Mg

Calcium Ca

Strontium Sr

Barium Ba

Radium Ra

The configuration of their valence shell is ns²

These elements are reactive but less reactive than the alkali earth metals.

They are typically metals with a high boiling and melting point. Due to their metallic nature, they are dense.

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements

In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison

%F in CaF₂ :

$\tt \%F=\dfrac{2.Ar~F}{MW~CaF_2}\times 100\%\\\\\%F=\dfrac{2.19}{78}\times 100\5=48.72\%$
