isotopes of the same element have different mass number
Mass numbers of isotopes are different.
They are called as isotopes in which mass number differ by emmision of radiation
the atomic mass
the Atomic Mass
Different isotopes of bromine have different numbers of neutrons, resulting in different mass numbers. Bromine-79 and bromine-81 are the two most common isotopes of bromine, with mass numbers of 79 and 81, respectively.
isotopes
Isotopes are identified by their mass numbers.
Isotopes can be identified by their atomic number and mass number. Isotopes of an element have the same number of protons but different numbers of neutrons. This difference in neutron count results in different mass numbers for each isotope. Scientists use mass spectrometry to measure the mass of isotopes and identify them based on their unique mass numbers.
the average mass numbers of the isotopes of an element
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Isotopes of the same element have different numbers of neutrons and mass.
Boron is both: Isotopes with mass numbers of 10 and 11 occur naturally, and isotopes with mass numbers of 8, 9, 12, and 13 have been synthesized.
