The number of protons in an atom can be determined by the element's atomic number, and the number of electrons can be determined by subtracting by atomic mass by the atomic number.
Answer:
. 1. This amino acid has a positively charged R group: ARGININE
2. This amino acid has a negatively charged R group: ASPARTATE
3. This amino acid has a neutral polar R group: NONE
4. This amino acid has a nonpolar aliphatic R: VALINE
5. This amino acid has an aromatic R group: TRYTOPHAN
Explanation:
1) Arginine contains an extra amino group bearing a positive charge, in its chain which imparts basic properties to it
2) Aspartate contains an extra carboxyl group with a dissociable protron. Once the Protron is dissociated, it carries an extra negative charge in its side chain (R)
3) NONE of the amino acids given belong to this group because amino acids with neutral polar R groups contain functional groups that form hydrogen bonds with water. But, this is not the case with tryptophan aspartate valine or arginine
4) Valine has a R group that is hydrocarbon in nature and thus hydrophobic.
5) Trytophan has a benzene ring in its side chain

Answer:
Liquid : A liquid has definite mass and it's volume does not change. It is hard to compress but flows easily. The shape of the liquid varies and depends on then shape of the container holding it.
Solid : A solid has a definite mass, definite shape and it's volume does not change. It does not flow and it is hard to compress.
Gas : A gas has a definite mass but it's volume can vary and it takes up the shape of container holding it. It flows easily and it is easy to compress.
