yes,because in isotopes neutrons differ from normal element.

How do you find atomic mass and mass number of isotope?
The atomic mass of an isotope is the weighted average of the masses of the naturally occurring isotopes of an element. It is found by multiplying the mass of each isotope by its natural abundance and summing these values. The mass number of an isotope is the total number of protons and neutrons in its nucleus and can be found by rounding the atomic mass to the nearest whole number.
How do you find the atomic mass and the atomic number?
The atomic number is the whole # on the periodic table or the # of protons in an atom. The atomic mass is the # that is not the whole # on the periodic table, or you can multiply the mass of the isotope by its abundance and add the answers together.
Correct nuclear notation for isotope -15?
Be, B, C, N, O and F have an isotope with the mass 15. Example for nitrogen: 157N (15 is the atomic mass of the isotope, 7 is the atomic number of nitrogen). For other elements, of course, the atomic number is different.
An isotope of chlorine has 25 protons and 17 neutrons what is the mass number of that isotope of chlorine?
The mass number of an isotope is the sum of its protons and neutrons. In this case, the isotope of chlorine has 25 protons and 17 neutrons. Therefore, the mass number is 25 + 17 = 42. Thus, the mass number of this isotope of chlorine is 42.
Why is the atomic mass of nobelium a whole number?
The atomic mass of nobelium reported as a whole number is usually the average atomic mass of its isotopes, taking into account the natural abundance of each isotope. Since this average is calculated from the weighted average of the isotopes' masses, the result often appears as a whole number.
How is an isotope and mass number related?
It isn't, as such. Isotopes of the same element have different numbers of neutrons, and neutrons have a mas of one atomic mass unit (amu). So isotopes have different atomic masses, but being told the number of neutrons any isotope has, will not enable you to say what element or atomic mass it had, unless you remembered the details for every single isotope. Even then different elements can have the same number of neutrons. Isotopes do get named after their atomic mass however - uranaium 235 has an atomic mass of 235, for instance.
What is the mass number of an oxygen isotope that has nine neutrons?
The mass number of an isotope is the sum of its protons and neutrons. For oxygen, which has 8 protons, an isotope with nine neutrons would have a mass number of 8 (protons) + 9 (neutrons) = 17. Therefore, the mass number of this oxygen isotope is 17. This isotope is known as oxygen-17.
What is the mass number of rutherfordium?
The isotope with the longest half life (Rf-267) has the mass number 267.Each isotope has a specific mass number.
What element has a mass number of 144?
Neodymium, Nd, has an isotope with a mass number of 144. Samarium, Sm, also has an isotope with a mass number of 144.
An isotope of radon has 86 protons and 137 neutrons what is the mass number of this isotopes?
An isotope of indium has 77 protons and 115 neutrons. What is the mass number of this isotope
How can you dertermine the number of neutrons in a isotope?
Subtract the atomic number of the isotope from its atomic mass number to obtain the number of neutrons in an isotope.
How does the atomic number relate to the number of protons in an atom?
Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)
