It's tiny crystals of calcium carbonate mixed with proteins, so calcium, carbon, hydrogen, oxygen, nitrogen, and probably a bit of sulfur as well.
no both iron and silicon are elements. chemical compounds aretwo or more elements.

The chemical symbol for radium on the periodic table of elements is Ra.
The chemical formula of guanine is C5H5N5O.
The elements are listed in the periodic table based on their chemical properties and atomic structure. The chemical formula represents the elements present in a compound, with the symbols of the elements and subscript numbers indicating the ratio of atoms. The elements are arranged in the periodic table in order of increasing atomic number.
nacre is the substance that covers a pearl naturally as it is forming
I believe it is is called nacre. I read that nacre is what pearls are formed from.
The force that attracts chemical elements to other elements is known as the ionic bond. This will attract and hold chemical elements together.
"Nacre" is not a type of pearl, but rather the material coating that creates a pearl. A pearl is made up of layers and layers of a substance called nacre -- calcium carbonate and protein. The thicker the nacre is, the more durable and valuable the pearl. The average thickness of a cultured pearl's nacre ranges from 1mm to 3mm. "Nacre" is a pearly substance that mollusks secrete around irritants. Thick, overlapping nacre layers create a strong luster and a valuable pearl. Thick nacre layers take years to build up. It can be used to determine whether a pearl is real.
The thickness of nacre, which is also known as mother-of-pearl, can vary depending on the type of mollusk it comes from. Typically, nacre can range from around 0.3 millimeters to 3 millimeters in thickness.

Chemical elements are no food, can't eat them. Shouldn't this question be rephrased into: "What are the chemical elements found in food?" ?

Now are known 118 chemical elements.
Symbols of chemical elements are derived from the chemical name.
Chemical elements are combined to produce chemical compounds.
