Atoms of different elements have the same mass .

Atoms of different elements with different atomic numbers, having the same mass number is known as ________

The atoms of different elements having same mass number but different atomic number are known as isobars. The sum of protons and neutrons, in the isobars is always different.

Atoms of different elements having the same number of neutrons but differnet atomic numbers are called

Assertion (A): Two atoms of different elements having same mass number but different atomic numbers are called isobars. Reason (R): Atomic number is the number of protons present and mass number is the total number of protons and neutrons present in a nucleus.

Two different elements may have same mass number but not the same __________________.

Assertion : ""_(14)Si^(30),""_(15)P^(31) and ""_(16)S^(32) are a group of isotones. Reason : Isotones are atoms of different elements having different mass numbers and atomic numbers but same number of neutrons in their nuclei.

Nuclides having the same atomic and mass numbers are known as
