It is not correct.
neutrons
Isotopes. They differ in the number of neutrons in the nucleus.
Isotopes must have the same atomic number, which is the number of protons. The atomic mass, which is the total number of protons and neutrons, varies for the different isotopes. so it should have different mass numbers..
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).
Isotopes of the same element have different numbers of neutrons in their atomic nuclei. This results in isotopes having slightly different atomic masses while maintaining the same number of protons (which determines the element's identity).
Masses.
Isotopes are elements that differ in the number of neutrons they have. Isotopes of an element have the same number of protons in their nuclei but different numbers of neutrons, resulting in varying atomic weights.
Different isotopes of an element differ in the number of neutrons and thus in their atomic weight.
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of ununquadium is114; uuq has five isotopes, each with a different number of isotopes..
They have the same number of protons and 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 for any given element varies, depending on the isotopes. Search the Wikipedia, or Google, for "Isotopes of Zirconium" for the isotopes of this particular element. The list of isotopes will give you the atomic mass (protons + neutrons) for the different isotopes; subtract the atomic number (which is the number of protons) to get the number of neutrons for each isotope.
