what are the isotopes.given on example
Answers
Answer:
The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotopeof a given element has a different mass number. For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively.
Answer:
Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number. All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.
Most common type:
The most common carbon isotope is carbon-12. Its name signifies that its nucleus contains six protons and six neutrons, for a total of 12. On Earth, carbon-12 accounts for almost 99 percent of naturally occurring carbon. Scientists use atomic mass units, or amu, to measure the mass of elements.
For example, carbon has six protons and is atomic number 6. Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons. Every element has its own number of isotopes.
