neutrons
Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.
The isotopes of an element have the same number of protons, but different numbers of neutrons.
Isotopes.
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
Isotopes of a chemical element have a similar number of protons but a different number of neutrons.
Isotopes of the same element have different number of neutrons.
Two different isotopes of an element have different numbers of neutrons. That's what an isotope is. So, no, isotopes of an element can not have the same number of neutrons.
The number of neutrons is different in isotopes of an element. Isotopes of the same element have the same number of protons (which defines the element) but different numbers of neutrons. This variation in neutron number gives rise to different atomic masses among isotopes of an element.
An atom or element that have different masses are known as isotopes.
Isotopes are atoms of the same element that are only different by the number of neutrons they have
They are isotopes of that element, they have different neutron numbers.
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.
If an atom of the same element has the same number of protons but a different number of neutrons, then they are isotopes.
Isotopes of the same element have a different number of neutrons.
This statement is incorrect. Isotopes of an element have the same number of protons but differ in their number of neutrons. Rubidium, specifically, has two stable isotopes: Rb-85 and Rb-87, which both have 37 protons but different numbers of neutrons.
The atomic number is the same for the all isotopes of a chemical element.
