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.

What is the atomic weight of the element potassium?
The atomic number of potassium is 19 and the atomic weight is 39.0983 grams per mole. See the Web Links to the left for a periodic table where you can find the atomic number and atomic weight of all the elements!
What is the number of protons in potassium ion?
There are 19 protons in a potassium atom, ion, and isotope. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons.
What is the atomic number of isotope?
Well all Isotopes have the same atomic number so if you have the element the atomic number of an element with that same isotope is that same atomic number.
Can All carbon atoms have the same atomic number?
Yes, all carbon atoms have the same atomic number, and that is 6.
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.
What is the atomic weight of the element potassium?
The atomic number of potassium is 19 and the atomic weight is 39.0983 grams per mole. See the Web Links to the left for a periodic table where you can find the atomic number and atomic weight of all the elements!

There are 19 protons in a potassium atom, ion, and isotope. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons.
What is the atomic number of isotope?
Well all Isotopes have the same atomic number so if you have the element the atomic number of an element with that same isotope is that same atomic number.
Can All carbon atoms have the same atomic number?
Yes, all carbon atoms have the same atomic number, and that is 6.
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.
What is the total number of protons in the nucleus of a potassium 42 isotope?
The atomic number of potassium is 19. This means that there are 19 protons in every potassium atom, regardless of isotope.
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.
What is a pure substance - all the atoms have the same atomic number or number of protons?
A pure substance in which all the atoms have the same atomic number or number of protons is an element.
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.
What do all atoms of the same elemnt have?
All atoms of the same element have the same number of protons in their atomic nuclei. The number of protons is the atomic number for that element on the periodic table. The elements are arranged in order of increasing atomic number on the periodic table.
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.
Why do isotopes 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.
