What of an element are chemically identical but differ in the number of neutrons in the nucleus?

Elements which are chemically identical (have the same number of protons) but different numbers of neutrons are called isotopes.
For example, the element H (hydrogen) has three naturally-occurring isotopes:
- Protium or H-1, with one proton and no neutrons (the most common form)
- Deuterium or H-2, with one proton and one neutron (quite rare)
- Tritium or H-3, with one proton and two neutrons (extremely rare)
Most elements have one distinctly common isotope. For example, the hydrogen in an ordinary glass of water is nearly 100% H-1, while the oxygen is nearly 100% O-16 (with 8 protons and 8 neutrons). Oxygen does occur naturally with 2 extra neutrons (O-18) and 1 extra neutron (O-17), but these isotopes are quite rare.

If an atom of element has a mass number of 271 and 161 neutrons in it's nucleus what is the atomic number of the element?
110. number of protons = mass number - neutrons = 271 - 261 = 110
How is the atomic number and mass number different?
The atomic number is the number of protons in the nucleus of an atom of any given element. The mass number is the number of protons and neutrons in the nucleus of an atom of an isotope of an element.
Is mass number the combining capacity of an element?
No, mass number is the number of neutrons and protons that exist within the nucleus of the atom for a particular element. It is based on the idea that most of the mass of an atom derives from the nucleus.
Are all atoms of a given element identical to one another and different from atoms of other elements?
No. Some may have different numbers of neutrons. Atoms of the same element (atoms with the same number of protons in the nucleus) may have different numbers of neutrons, and so will have different masses. As an example, chlorine is a mixture of different isotopes with some of the atoms having different neutrons numbers.
Why is proton number of an atom of an element different from the nucleon number of an atom of an element?
The difference between proton number (which is atomic number) and nucleon number, which is the number of protons and neutrons in an atom's nucleus, is the number of neutrons in the nucleus of a given nuclide. Nucleons are the components of an atomic nucleus. We know that both protons and neutrons make up an atom's nucleus. So the number of nucleons, which is the number of protons and neutrons, minus the number of protons, will equal the number of neutrons in the atomic nucleus.
Do isotopes have a nucleus?
Yes. Isotopes are simply normal elements with a different number of constituent neutrons in their nucleus. All isotopes have a nucleus with an identical number of protons to its element.
Where is the neutrons located at on an element on the pt element?
All neutrons (of all elements) are located in the nucleus (as all ptotons are)
What make up the nucleus and are made up of what?
The nucleus is made of protons, neutrons and electrons. These element move in and out of the nucleus depending on the external environment.
What is something and atom and isotope have in common?
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.
How are isotopes the same but different?
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.
How many neutrons are in the nucleus in the element plutonium?
678
Which solid element has 135 neutrons in its nucleus?
Untripentium
How many neutrons are in the nucleus of the element 'p'?
16
What is the smallest unit showing properties of the element Protons and Neutrons in nucleus?
The smallest unit that shows the properties of an element is an atom, and yes, an atom has protons and neutrons in the nucleus.
Where are protons and neutrons of an atom contained?
The nucleus of an atom contains protons and neutrons. Different amount of neutrons- Isotopes. Different amount of protons- Different element.
What element is the number of protons and neutrons in the nucleus?
All elements have neutrons and protons within the nucleus.
How does the mass of a nucleus differ from the mass of an electron?
There is no simple answer.The mass of a nucleus depends on the number of neutrons and protons in the nucleus. The number of protons in the nucleus depends on the element. Moreover, the number of neutrons can vary between isotopes of the same element.
