Answer: Protons
Explanation: Every atom is defined by its protons every element. So if it has 1 proton its hydrogen no matter what. If it has 2 protons its helium no matter what and so on. So if you know the number of protons you know the element.
The atomic number tells you the number of protons that are in the core of a particular element.
Glutamic acid is a hydrophilic amino acid. At physiological pH, it is negatively charged. Carboxylic acid group ( -COOH ) in its side chain is responsible for both, the hydrophilic nature as well as negative charge of the glutamic acid. Because of its hydrophilic nature it is found on the surface of protein facing aqueous solution i.e. it is an extrinsic amino acid.
Valine on the other hand is a hydrophobic amino acid. It is neutral at physiological pH. Valine has an aliphatic side chain which is responsible for both, it's hydrophobic nature as well as neutral charge. Since it is hydrophobic, it is found inside of protein molecules i.e. it is an intrinsic amino acid.
