what is the role of mass number in the production of medical radioisotopes?

Nov 22, 2024 ... This approximation of mass can be used to easily calculate how many neutrons an element has by simply subtracting the number of protons from the ... The correct answer is (D) The nucleus contains both protons and neutrons, the sum of which determines the mass number. atomic number=14Si28 = mass number. The mass number is 28, which tells us that silicon has a total number of protons and neutrons that equals 28. As we ...

Specifically, the atomic number corresponds to the number of protons found in the nucleus of an atom. Since each element on the periodic table has a unique ... Mass number of the most abundant isotope of the element with atomic number Z ... number equal to n. If there is no stable isotope, choose the one with ... The number of neutrons in the nucleus is equal to A minus Z. chemical symbol. Two different forms, or isotopes, of carbon are shown below: Carbon-12: with 6 ... The number of electrons in an atom is normally equal to the number of protons in the nucleus. ... Hence the nominal mass, based on the mass number, approximates ...
