Question

differentiate between mass number and atomic number​

Answer 1

Answer:

Difference Between Atomic Mass and Atomic NumberAtomic MassAtomic NumberAtomic 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.Atomic mass is denoted by AThe 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 elementIsotopes only share the same atomic number.Atomic mass is mostly measured using atomic mass unit (amu).Atomic number is just a digit that is used to place elements in a periodic table.

$\bf{\underline{Mass \: number}}$

The mass number, also called atomic mass number or nucleon number, is the total number of protons and neutrons in an atomic nucleus. It is approximately equal to the atomic mass of the atom expressed in atomic mass units.

$\bf{\underline{Atomic \: number}}$

The atomic number or proton number of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus
