How are isotopes different from one another?

Answer 1

Isotopes are atoms that have the same number of protons, but different number of neutrons in the nucleus of the atom. So the Carbon atom normally has 12 protons and 12 neutrons, but a few carbon atoms have 12 protons and 14 neutrons.

The number of protons in the nucleus and electrons in the shell determine the properties of the element, but the extra neutrons can cause the element to be a little heavier or lighter than normal.

Answer 2

Different Isotopes have the same number of protons, so they have the same atomic number, but have a different number of neutrons in the nucleus.

The different number of neutrons can make the atom more or less stable, sometimes leading to radioactive decay.

Answer 3

Isotopes of an element have the same number of protons but different numbers of neutrons. This leads to variations in Atomic Mass. Isotopes have similar chemical properties but may exhibit different physical properties, such as stability and radioactive decay rates.
