Every atom of the same element will have the same atomic number.
I.E. Hydrogen (H) will always have an atomic number of 1.
However an atom can have different atomic masses due to different isotopes.

∙ 7y agoThe definition of an isotope is that it is one of two or more atoms with the same atomic number (i.e. the same number of protons) but a different mass number (due to having a different number of neutrons).

NO!!!
Taking hydrogen as an example. It has three isotopes
#1 ; protium ; 1 proton and 1 electron ; mass = 1
#2 ; deuterium ; 1 proton , 1 electron and one neutron ; mass = 2
#3 ; tritium ; 1 proton 1 electron and 2 neutrons ; mass = 3

∙ 9y agoAll isotopes of an element have the same atomic number because they have the same number of protons. However, they have a different mass because they have a different number of neutrons.
Wiki User
∙ 12y agoNo! If they all had the same mass number, they would not be isotopes.
Wiki User
∙ 11y agoYes, the atomic number is a count of the number of protons an atom/element has. All isotopes of a specific element have the SAME atomic number but differing Atomic Mass.

∙ 7y agoIsotopes of a chemical element have the same atomic number; the number of neutrons is different.

What do two different neutral isotopes of the same element have in common nuclear number atomic mass nuclear mass atomic number?
The atomic number is the same for all isotopes.
How do the atomic number of the different isotopes an element compare?
The atomic number is the same for the all isotopes of a chemical element.
Why some isotopes were written without its atomic number?
Different isotopes of an element have the same atomic number, they (only) differ in (atomic) mass NUMBER.
Atoms of same chemical element that have different atomic mass are known as?
Isotopes. They differ in the number of neutrons in the nucleus.
Why do isotopes must have the same atomic number?
Not a question of why. It just is, isotopes have the same atomic number, (which means that they are all the same element) with different neutron numbers.
What atoms with same atomic number but different atomic masses?
Isotopes of the same element have the same number of protons (atomic number) but differ in number of neutrons (hence atomic masses).
Do isotopes have the same A number?
The atomic number is the same for the isotopes of a chemical element.
Do isotopes have the same atomic number and the same atomic mass?
No: They have the same atomic number but not the same atomic mass.
Do the atomic number of isotopes differ?
No. Isotopes have the same atomic number, protons and electrons. They have different neutrons.
Isotopes can have the same?
Atomic number

The atomic number is the same for the all isotopes of a chemical element.
Atoms of the same atomic are called what?
isotopes Atoms of the same element are called Isotopes. they have the same number of atoms (i.e. same atomic number) but different number of neutrons

Atoms of same chemical element that have different atomic mass are known as?
Isotopes. They differ in the number of neutrons in the nucleus.
Atoms that have the same atomic numbers but different atomic weights are called what?
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
