Many elements have different isotopes: 1) Carbon - Carbon 12, Carbon 14 2) Hydrogen - Protium, Deuterium, Tritium 3) Chlorine - Chlorine 35, Chlorine 37 etc
All elements have isotopes, but not all elements have naturally occurring isotopes.
Isotopes have the same number of protons and electrons but the number of neutrons is different.
Dear questioner,As an answer to your question I should mention there are atoms which have the same number of protons but are considered different. These atoms are called Isotopes. Isotopes of an element have the same number of protons but the number of Neutrons are not the same. Isotopes have the same chemical virtues but in the physical virtues related to mass they are a bit different.
Mostly COHN : carbon, oxygen, hydrogen, nitrogen. Everything else is just trace elements.
Pure elements. Isotopes. Atoms.
Atoms form millions of molecules
The chemical nature of an element is determined (mainly) by the electronic configuration in the outermost shells. However, most elements have isotopes - atomic configurations that have the same outer shells, but which may have a different number of neutrons in the atom core. This gives them the same chemical nature, but a different mass. Many isotopes are unstable in the long run - they will spontaneously disintegrate.
Isotopes are atoms of the same elements with different number of neutrons.
elements are isotopes, when different atoms of the same element have different number of neutrons
Since you have isotopes of elements. Isotopes are elements with different number of neutrons hence why the different atomic masses for the same elements.
Yes, it is true.
Isotopes differ in the number of neutrons they possess.
The atomic number of the isotopes of an element is identical; the mass number is different.
Uranium has a number of isotopes including U235 and U238, both of which are radioactive
Isotopes of an element have different masses because their nuclei have different numbers of neutrons.

Because of the difference in mass number. Isotopes must have different numbers of neutrons.
Elements can exist in the form of different isotopes. Isotopes of the same element have the same number of protons in their nuclei but have different numbers of neutrons. The first gives them the same atomic number and chemical properties while the second gives them different atomic weights.
