Question

1. What is difference between atomic number and atomic mass number? Give a
symbolical representation of a nuclide( physics 10th class)​

Answer 1

Answer:

The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom

Answer 2

Answer:

Atomic mass is associated with the number of neutrons and protons that are present in a particular nucleus of an element. Atomic number is usually the number of protons present in an element's nucleus. It is the average weight of an element. It is the total number of nucleons in the atom's nucleus.

Explanation:

Nuclides are commonly expressed in the form AZX, where A denotes the total number of protons and neutrons, Z represents the number of protons, and the difference between A and Z is the number of neutrons.
