Answer 2

Answer:

Atomic Mass :- Atomic mass is associated with the number of neutrons and protons that are present in a particular nucleus of an element. Atomic mass is denoted by A The letter Z is used to represent an atomic number. Atomic mass cannot be be used to define the type of element. Atomic number mainly helps in the classification and identification of an element. Atomic mass is also used to classify different isotopes of the same element Isotopes only share the same atomic number. Atomic mass is mostly measured using atomic mass unit (amu). It is the average weight of an element. It is the total number of nucleons in the atom’s nucleus.

Atomic number :- Even the proton number is called the atomic number. Atomic number is usually the number of protons present in an element’s nucleus. A chemical element’s atomic no. is defined as the sum of protons present in the nucleus of that atom of the element. Since neutrons carry no net electrical charge it is the charge number of the nucleus.
