Answer: element symbol : Cu.

Number of protons= 29

Number of electrons = 29

Explanation:

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons   (i)

Atomic number is defined as the number of protons or number of electrons that are present in an atom in a neutral element.

Atomic number = Number of electrons = Number of protons   (ii)

Given mass number = 65

Number of neutrons  = 36

using (i) , Mass number = Number of protons + Number of neutrons

65=  Number of protons + 36

Number of protons = 29

Using (ii) ,  Atomic number  = Number of protons = Number of electrons  = 29

Thus the element is copper with atomic number of 29 and element symbol is Cu.

Answer:

Is an isotope of Cu (Copper)

Explanation:

Remember that the mass number will tell you the number of protons and neutrons. If you have the mass number(65) and the number of neutrons (36), you just need to subtract: 65 - 36 = 29 the number or protons.

As this is a neutral isotope, that means that is going to have the same number of protons and electrons, that is 29.

Explain transmethylation reaction of amino acids.
tester [92]

Answer:Transamination, a chemical reaction that transfers an amino group to a ketoacid to form new amino acids. This pathway is responsible for the deamination of most amino acids. This is one of the major degradation pathways which convert essential amino acids to non-essential amino acids (amino acids that can be synthesized de novo by the organism).

PLEASE HELP!!!<br><br> What is the mass of one lead atom in amu?
alexandr402 [8]

Answer: 207.2

Explanation:

In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass. This is approximately 1.67377 x 10 -27 kilogram (kg), or 1.67377 x 10 -24 gram (g). The mass of an atom in AMU is roughly equal to the sum of the number of protons and neutrons in the nucleus.
