A definitive answer is Isotopes of an element have a different number of neutrons. They have the same number of protons and electrons.

Here's two examples of isotopes.

#1 Hydrogen.

protium ; 1 p roton , 1 electrons, 0 neutrons ( The commonest isotope)

deuterium ; 1 proton , 1 elelctrons, 1 neutrons (knopwn as 'heavy hydrogen'(

tritium ; 1 protno, 1 electrons , 2 neutrons ) Radio- active and the rarest isotope_.

#2 Chlorine

Chlorine-35 ; 17 protons, 17 electrons, 18 neutrons.

Chlorine-37 ' 17 protonds, 17 electrons , 20 neutrons.

Because both isotopes of Chlorine are very common and in the ratios of 35:37 :: 3:1 it is averafes out to five an Atomic Mass od 35,5 .

There are many more isotopes in elements in the Periodic Table.

NB do NOT confuse with neither Allotropes nor Ions. both are different species from isotopes.

The isotopes of an element have the same number of protons, but different numbers of neutrons.


Which atoms that are same element and have the same number of protons but have different number of neutrons?

Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. An example is carbon-12 and carbon-14, which both have six protons but differ in the number of neutrons they possess.


What are atoms that have different masses but the number of protons?

Atoms that have different masses but the same number of protons are called isotopes. Isotopes of an element have the same number of protons, which determines the element's identity, but a different number of neutrons, leading to variations in atomic mass.


What structural element do all isotopes of an element have in common?

All isotopes of an element have the same number of protons in their nucleus. This is what defines them as being the same chemical element. The number of protons determines the element's atomic number.


Isotopes are atoms that have the same number of protons but a different?

Isotopes are atoms of a given element that have the same number of protons but a different mass number and therefore a different number of neutrons.


Atom of an element with a different number of protons?

This is not possible. The number of protons identifies an element, and all of the atoms of the same element have the same number of protons. The atoms of an element can, however, have different numbers of neutrons, and they are called isotopes.


Two atoms are isotopes of the same element which should be the same for these two atoms?

The number of protons in the nucleus is the same for both isotopes since they are of the same element. Isotopes of the same element have the same number of protons (which determines the element) but a different number of neutrons, leading to a difference in atomic mass.


Do all atoms of the same element contain the same number of netrons?

No, atoms of the same element have the same number of protons. Atoms of the same element with different numbers of neutrons are called isotopes.


Are atoms of the same element that have the same number of protons but have different number of neutrons?

Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.


What do isotopes and nucleus have in common?

Isotopes and nuclei are both related to atoms. Isotopes are atoms of the same element with different numbers of neutrons in their nuclei. The nucleus is the central part of an atom that contains protons and neutrons.


What do you call atoms of the same element such as Chlorine which have the same number of protons but different number of neutrons?

Isotopes.
