Answer:
All atoms have a dense central core called the atomic nucleus. Forming the nucleus are two kinds of particles: protons. which have a positive electrical charge, and neutrons, which have no charge. All atoms have at least one proton in their core, and the number of proton determines which kind of element an atom is
Explanation:
Yes , the nuclear mass or the charge of the nucleus does determine what element an atom is.
What is nuclear charge?
- The nuclear charge is the total charge in the nucleus for all the protons.
- It has the same value as the number of atoms.
- nuclear charge is equal to the atomic number (Z) for an ordinary nuclei.
- As we move forward in periodic table , the number of protons present in the nucleus of an element will increase.
- So, the nuclear charge will also increase .
- Therefore , we can say that there is different nuclear charge for different element.
What is nuclear mass?
- Nuclear mass is the mass of all the nucleons present inside the nucleus.
- It is calculated by M=ZM_(p)+(A-Z)M_(n).
- Where , M_(p) and M_(n) are mass of protons and neutrons respectively .
Thus, we can say that the nuclear mass or the charge of the nucleus does determine what element an atom is.
