Same:
* Atomic Number (Number of Protons): Isotopes of the same element have the same number of protons. This defines the element.
* Chemical Properties: Isotopes of the same element generally have the same chemical properties because they have the same number of electrons involved in chemical bonding.
Different:
* Mass Number (Number of Protons + Neutrons): Isotopes differ in the number of neutrons they contain. This is why isotopes of the same element have different atomic masses.
* Physical Properties: Isotopes can have slightly different physical properties, such as melting point, boiling point, and density.
Example:
Carbon-12 and Carbon-14 are both isotopes of carbon. They have the same number of protons (6), but Carbon-14 has 8 neutrons while Carbon-12 has 6 neutrons.
