Atomic Mass is the number of protons in an atom
mass number is the number of protons plus neutrons in an atom
What else can I help you with?
Does an isotope of an element have a different atomic mass?
Yes, isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in atomic mass. This is why the atomic mass on the periodic table is often listed as a range for an element.
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
How do the atomic mass numbers of different isotopes of an element compare?
The different isotopes have different atomic mass numbers, because the isotope has different numbers of neutrons. The protons and electrons are the same, so the change in mass number is the same as the change in the number of neutrons.
Why can an atom have more then one mass number but only one atomic number?
First of all, an atom can not literally have either more than one mass number or more than one atomic number. Different atoms of the same element can have different mass numbers but the same atomic number because the atomic number is the defining characteristic of an element, but many elements have isotopes that have different numbers of neutrons in their nuclei and therefore different mass numbers: Mass numbers are the sum of the numbers of protons and neutrons in the nucleus.
What is it called when they have same atomic number but different mass?
They are called isotopes of the same element
Do isotopes of an element have the same atomic mass but different atomic number?
The different mass numbers are due to different numbers of neutrons.
Isotopes of hydrogen have different atomic what?
Atomic mass and different numbers of neutrons.

The different isotopes have different atomic mass numbers, because the isotope has different numbers of neutrons. The protons and electrons are the same, so the change in mass number is the same as the change in the number of neutrons.
Do isotopes have the same atomic number and different mass numbers?
Yes. Isotopes have the same atomic number because all of their atoms have the same number of protons. They have different mass numbers because their atoms have different numbers of neutrons, and mass number is the sum of the numbers of protons and neutrons.
How can different atoms of the same element have the same atomic number but can have different mass numbers?
They have different numbers of neutrons.

What is the atom with same atomic number but different mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What are the atoms called then they have the same atomic number but different mass numbers?
They are called as isotopes in which mass number differ by emmision of radiation
Why are the atomic mass numbers of an element not hole numbers?
Its the average of the weight of the different isotopes of that element.
What is it called when they have same atomic number but different mass?
They are called isotopes of the same element
