Question

what is atomic mass, atomic number, Isotopes and Isobars​

Answer 1

Answer:

the number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.

The atomic mass is the mass of an atom. Although the SI unit of mass is kilogram, the atomic mass is often expressed in the non-SI unit dalton where 1 dalton is defined as ¹⁄₁₂ of the mass of a single carbon-12 atom, at rest.

Answer 2

ATOMIC MASS:

IT IS THE ALGEBRIC SUM OF NUMBER OF PROTONS AND NEUTRONS IN THE NUCLEUS OF THE ATOM.

ATOMIC NUMBER:

IT IS THE NUMBER OF PROTONS OR ELECTRONS OF A NEUTRAL ATOM.

ISOTOPES:

IF TWO ELEMENTS AS SAME ATOMIC NUMBER BUT DIFFERENT ATOMIC MASS THEN THEY ARE KNOWN AS ISOTOPES.

ISOBARS:

IF TWO ELEMENTS AS SAME ATOMIC MASS BUT DIFFERENT ATOMIC NUMBER THEN THEY ARE KNOWN AS ISOBARS.
