Examine the false statement. the alkali earth metals have five valence electrons. select the rewording of the statement that is true. the alkali earth metals have one valence electron. the alkali earth metals have two valence electrons. the halogens have five valence electrons. the alkali metals have five valence electrons.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
