Question

What are isotopes?Give example also.​

Answer 1

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.[1] The term isotope is formed from the Greek roots isos and topos meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table.

example; hydrogen , protium..,

Answer 2

One member of a family of chemical elements that has the same chemical properties (the same atomic number) but differs in mass. Isotopes have the same number of protons and electrons, but a different number of neutrons.

Some examples of stable isotopes are isotopes of carbon, potassium, calcium and vanadium. Radioactive isotopes have an unstable combination of protons and neutrons, so they have unstable nuclei. Because these isotopes are unstable, they undergo decay, and in the process can emit alpha, beta and gamma rays
