There are 20 different type of monomers present in proteins.
Amino acids are in reality the monomers of proteins. Out of the 20 amino acids,
only 9 are considered essential. The other 11 are of little use to the humans.
The nine of the essential amino acids required by humans are Tryptophan,
lysine, Histidine, Isoleucine, Valine, Threonine, Phenylalanine, Methionine and
Leucine. The amino acids combine with one another to form different types of
proteins. These proteins satisfy a number of our physical functional needs.

Answer:
Isotopes have same atomic numbers, no. of protons and no. of electrons. Only their no. of neutrons and atomic mass are changed.
<u>Na - 24:</u>
Atomic Mass = 24
Atomic No. = 11
Hence,
No. of protons in Na-24 = 11
No. of neutrons = Atomic Mass - Atomic Number
No. of neutrons = 24 - 11
No. of neutrons = 13
Atomic Number = 11

Explanation:
Hey there!
Your answer is B. MgCl.
This is because this isn't an actual existing compound.
Water (H₂O) and magnesium chloride (MgCl₂) are both real compounds, but the number of electrons does not line up to make MgCl possible.
Hope this helps!
