Also asked, what is atomic mass and atomic number?
Experimental data showed that the vast majority of the mass of an atom is concentrated in its nucleus, which is composed of protons and neutrons. The mass number (represented by the letter A) is defined as the total number of protons and neutrons in an atom.
Likewise, what is difference between atomic weight and atomic number? As per the definitions that have been provided, atomic mass which is also called atomic weight is the measured average mass of an atom of an element. Whereas, atomic number is nothing but the total number of neutrons and protons in the nucleus of an atom.
Keeping this in consideration, are the atomic number and mass number the same?
Mass Number. An element's mass number (A) is the sum of the number of protons and the number of neutrons. Protons and neutrons both weigh about one atomic mass unit or amu. Isotopes of the same element will have the same atomic number but different mass numbers.
What is atomic mass number?
The mass number (symbol A, from the German word Atomgewicht [atomic weight]), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. The mass number is different for each different isotope of a chemical element.
