No, because some elements have Isotopes, with the same Proton number but different Neutron numbers. Sometimes therefore, the neutron number can overlap with that of isotopes of other elements. For example, two of Helium's isotopes share neutron numbers with two of Hydrogen's isotopes.
Deuterium has 1 neutron, and so does 3He,
Tritium has 2 neutrons, and so does 4He.
It is the number of protons which determines which element it is.

∙ 11y agoYes, the number of protons is the atomic number. Every element has a specific atomic number and no two elements have the same one.
Wiki User
∙ 8y agoYou can never characterize an element by the number of neutrons. It is the number of PROTONS that is characteristic.
Wiki User
∙ 7y agoYes, because the number of protons is equal to the atomic number.

Can you use the mass number of an element to determine the number of electrons in an atom?
Mass number = number of protons + number of neutrons Number of electrons = number of protons = mass number of an isotope - number of neutrons
Can the mass number of an element be used to determine the number of electrons in an atom?
No. The mass number can be used, however, to determine the number of neutrons. Electrons can only be determined by knowing the atom's charge.
Finding the number of neutrons in an element?
Number of neutrons = mass number - number of protons
Carbon 12 and carbon 13 are different in the number of what?
Neutrons. The number of protons is ALWAYS the same for the same element. Different forms of the same element, called isotopes, differ in the number of neutrons only and will react chemically in exactly the same way.
Carbon has an atomic number of 6 how many protons and neutrons are in a nucleus of carbon 13?
12 - 6 = 6 neutrons; the number of neutrons in an isotope is always the mass number minus the atomic number.
Why must you know both how many protons and how many neutrons an element has in order to fully identify it?
The number of protons determine what element it is, the number of neutrons determine what isotope it is.
How do you determine neutrons in element?
subtract the atomic number from the mass number
Is it true Different isotopes for the same element will always have the same numbers of neutrons?
Yes. it is true. Isotopes of the same element always have different number of neutrons.
Can you have a different number of neutrons and still have the same element?
yes you can have a different number of neutrons and have an isotope of the same element.number of protons for a element always stays the same.
Do the nuclei of all atoms of a given element always have the same number of neutrons?
No - different isotopes of an element have different numbers of neutrons. All atoms of an element will have the same number of protons.
What information could you use to determine the atomic number of unknown element that has a mass number of 22?
number of neutrons
Can you use the mass number of an element to determine the number of electrons in an atom?
Mass number = number of protons + number of neutrons Number of electrons = number of protons = mass number of an isotope - number of neutrons
What determines the different isotopes from an atom?
The name of the element and the mass number (number of protons + neutrons) it is written e.g Uranium-235 or symbolically 235U
What is an element with 20 neutrons?
Calcium-40: The atomic number of calcium is 20 and the number of neutrons is always the difference between the atomic mass and the atomic number.
A chlorine atom with 18 neutrons is what element?
A chlorine atoms is always a molecule of chlorine, irrespective of the number of neutrons it may have.
How is the nucleus related to the periodic table?
The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.
What do protons determine about an element?
The protons of an element determine the atomic number, also known as the proton number. Do not confuse this with mass number which is the number of protons and neutrons.
