elements can be found in nature. some atoms of a given element may have different mass numbers. their atomic numbers, however, are the same. these are known as isotopes. isotopes are thus defined as different atoms of the same element with the same atomic number but different mass numbers....
Atomic Mass of First 30 Elements - Atomic Mass of Elements is Measured with the Help of its Unit - Atomic Mass Unit. One such Unit is Equal to One-Twelfth of the Mass of a Carbon-12 Atom Which is at Rest. Learn about Atomic Mass of First 30 Elements at B

As a result, neutrons have no charge, and adding them to an atom changes its atomic mass. When neutrons are added to the nucleus, however, the nuclear radius changes. Q5 Who discovered the atomic radius? Radioactivity piqued Ernest Rutherford’s interest. He spent twenty years researching it,...
