They are isotopes of that element, they have different neutron numbers.

What is it called when they have same atomic number but different mass?
They are called isotopes of the same element
What is an element that has the same atomic number but different mass numbers?
If a sample of an element contains atoms of different mass numbers, the name of the element followed by a hyphen and the mass number is the name of an isotope of the element.
What do you call atoms of the same element with different atomic masses?
They are called isotopes. They have different mass nmbers because they have a different number of neutrons.
What is the term for atoms of two atoms of the same element with different molecular mass?
They are called isotopes. They differ in molecular mass due to the different number of neutrons.
Why do two isotopes of an element have the same atomic number but differnent mass number?
Because the atomic number is the number of protons in an element. If you change the atomic number you will have a completely different element. The mass number changes because the number of neutrons is different.

Why do isotopes of an element have the same atomic number but different mass numbers?
An element's atomic number refers to the number of protons in its nucleus, and this number never varies - an atom with a different number of protons becomes a different element; i.e. an element with one proton is called hydrogen, an element with 2 protons is helium, 3 protons means it's lithium etc). Usually there are the same number of neutrons as there are protons, but this number can vary, and when an element doesn't have the standard number of neutrons it's called an isotope. The mass number of an element is the sum of the number of protons plusneutrons, which is why this number can is different for different isotopes.

What are isotopes and their differences?
Atoms of same element with same atomic number,which have different mass number is called isotops.
What atom of an element with a different number of neutrons?
Isotopes.

Do both isotopes have the same mass number?
An Isotope of an element is an atom that has the same number of protons, (number of protons is the defining feature of an element) but different number of neutrons.Because The mass number is the sum of protons and neutrons, different isotopes have different mass numbers.
What is it called when atoms of the same element that have a different atomic weight?
Atoms with the same atomic number (number of protons), but different mass numbers (i.e. different mass) are called isotopes. The difference in mass is due to different numbers of neutrons. For more info: http://en.wikipedia.org/wiki/Isotope
Does an isotope of an element have a different atomic mass?
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
How are the atomic mass and the atomic number different?
the atomic mass is the number of protons and neutrons in an atom of an element and the atomic number is the number of protons of an atom of an element.
