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.
The 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
All 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.
No! If they all had the same mass number, they would not be isotopes.
Yes, 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.
Isotopes of a chemical element have the same atomic number; the number of neutrons is different.
The atomic number is the same for all isotopes.
The atomic number is the same for the all isotopes of a chemical element.
Different isotopes of an element have the same atomic number, they (only) differ in (atomic) mass NUMBER.
Isotopes. They differ in the number of neutrons in the nucleus.
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.
Isotopes of the same element have the same number of protons (atomic number) but differ in number of neutrons (hence atomic masses).
The atomic number is the same for the isotopes of a chemical element.
No: They have the same atomic number but not the same atomic mass.
No. Isotopes have the same atomic number, protons and electrons. They have different neutrons.

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

Isotopes. They differ in the number of neutrons in the nucleus.
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
