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.
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.
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.
How is an isotope and a mass number related?
An isotope is member of an element of Mass Number differing from the average; for example, the most common isotope of Carbon is 12C (6 protons, 6 neutrons), where 13C and 14C would be less common (even unstable, radioactive) isotopes. So isotopes are varying forms of an element, differing in mass number.
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)
What is the mass number of an oxygen isotope that has 9 neutrons?
The mass number of an isotope is the sum of its protons and neutrons. Oxygen has an atomic number of 8, meaning it has 8 protons. If the isotope has 9 neutrons, the mass number would be 8 protons + 9 neutrons = 17. Therefore, the mass number of this oxygen isotope is 17.
What is radiums mass number?
The most stable isotope of radium - 226Ra - has the atomic mass 226,025 409 8 (25).
What does the atomic mass equals the number of?
An isotope's mass number is the sum of the protons and neutrons in each atomic nucleus of the isotope.
