What types of atoms are shown in a skeletal model of an organic molecule?
a. atoms of every element except carbon
b. atoms of every element except hydrogen
c. atoms of every element
d. atoms of every element except carbon and hydrogen

Answer:

Atoms of every element are shown in a skeletal model of an organic molecule.

Explanation:

Skeletal model of an organic molecule consists of various skeletal atoms that are used in making up of the molecule. Various conventions of  hydrogen and  carbon  atoms are employed in it. The molecules bonding and certain representation of molecular geometry are shown in the structural formula.

Use of skeletal formula is ubiquitous in organic chemistry. Thus, in organic chemistry atoms of every element are shown in the skeletal model of an organic molecule

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).
