Which of the following pairs of elements is most likely to form an ionic compound? a. magnesium and fluorine b. nitrogen and sulfur c. oxygen and chlorine d. sodium and aluminum

A. magnesium and fluorine

Explanation:

Ionic bond is the bond which is formed between the two oppositely charged ions and are held by the strong electrostatic attraction. This is formed between the atoms which have high differing electronegativities. It is usually the bond which is formed between a nonmetal and a metal.

Thus,  A. magnesium and fluorine will form an ionic bond as magnesium is metal and fluorine is nonmetal and forms

Out of options, B. nitrogen and sulfur C. oxygen and chlorine, the elements mentioned are all nonmetals and can not form ionic bond.

D. sodium and aluminum both are metals and thus cannot form ionic bond.

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).
