Yes. The atomic number is the number of protons in an atom. Potassium always has 19 protons, and so its atomic number is 19. As soon as there is a change in the number of protons, then the element is different.

Yes, all carbon atoms have the same atomic number, and that is 6.


Why do all atoms of an element have the same atomic number?

The atomic number represents the number of protons in an atom's nucleus, which determines the element's identity. All atoms of the same element have the same number of protons in their nucleus, hence they all have the same atomic number.


Do all of the same elements have the same atomic number?

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.


Do all of the elements have the same atomic number?

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.


How does potassium-19 differ from potassium-41?

The nomenclature "potassium-19" is not commonly used because it is redundant. The 19 in potassium-19 would indicate the number of protons in potassium. All isotopes of potassium have 19 protons. Therefore 19 is known as the atomic number of potassium. Potassium-41 is one of the three naturally occurring isotopes of potassium. It has 19 protons and 22 neutrons, giving it an atomic mass number of 41.
