Almost all the elements have different isotopes having same atomic no but different mass no or neutrons.
neutrons
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.
The number of neutrons in the nucleus is different in each isotope of an element. Isotopes of an element have the same number of protons (atomic number) but different numbers of neutrons, leading to variations in atomic mass.
Isotopes are different atoms of the same element with a different atomic mass. This difference is caused by a different number of neutrons.
Each isotope of an element has a different number of neutrons: Atomic mass of the isotope - Atomic number = Number of neutrons
To find the number of neutrons in an element, you need to know its atomic mass (rounded to the nearest whole number) and its atomic number. The atomic number represents the number of protons in the nucleus, and since the number of neutrons can vary (resulting in different isotopes), you can calculate the number of neutrons by subtracting the atomic number from the atomic mass: Neutrons = Atomic Mass - Atomic Number. For example, if an element has an atomic mass of 12 and an atomic number of 6, it has 12 - 6 = 6 neutrons.
They have the same number of protons and different number of neutrons.
It is an isotope of the element.
Masses.
Isotopes of the same element have different numbers of neutrons in their atomic nuclei. This results in isotopes having slightly different atomic masses while maintaining the same number of protons (which determines the element's identity).
The isotopes of an element must have a different amount of neutrons. I'm pretty sure you know what these are, but just in case: A neutron is a sub-atomic part of an atom, together with protons and electrons.
Isotopes are atoms that have the same number of protons and electrons. They have the same atomic number on the periodic table but they have a different number of neutrons and so they have different mass. Isotopes of the same element can have different chemical properties.
