Atomic number is a measure of protons and electrons. extra or less Neutrons are what make an isotope and are not included in atomic number. therefore element with the highest atomic number will also be the isotope with the highest atomic number. on my Periodic Table it is lawrencium at 103. (note although this might have extra neutrons making it an isotope, it will always have the same atomic number - atomic number isn't what determines an isotope it is mass number)
if you meant mass number (which is what determines an isotope), you can subtract the atomic number from the mass number to find out how many neutrons there are and determine whether it is an isotope or not

What is the isotope for mass number 54 and contains 24 protons?
Any isotope with 24 protons is chromium; therefore, the requested isotope is 54Cr.
What is the mass number for a sulfur atom that contains 31 neutrons?
Each sulfur atom contains 16 protons; the mass number is the sum of the numbers of protons and neutrons; therefore, 47. (It is unlikely that such a heavy isotope of sulfur actually exists.)
An isotope of nitrogen could have more protons neutron electrons?
Each isotope has the same number of protons and electrons but a different number of neutrons.
How many protons neutrons does oxygen have?
oxygen has 8 protons as its atomic number is 8. The number of neutrons depends on the isotope. O-15 isotope will have 7 neutrons, O-16 isotope will have 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
How may protons neutrons and electrons In lawrencium?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element; the atomic number of Lr is 103. Lawrencium has many isotopes and each isotope has a different number of neutrons.
What isotope has 20 protons and 22 neutrons?
The number on the periodic table is the number of protons it contains. The isotope number is the sum of the protons and neutrons.Therefore, the isotope with 20 protons and 22 neutrons is Calcium-42.
What is the isotope for mass number 54 and contains 24 protons?
Any isotope with 24 protons is chromium; therefore, the requested isotope is 54Cr.
What is the term for an atom that contains a different number of electrons and protons?
An isotope.
Sulfer-32 isotope contains how many protons?
16 protons in a sulfur-32 isotope because keep in mind that the number of protons in a chemical determines what that chemical is so its not even reasonable to ask how many protons does a sulfur-32 isotope have.
The isotope of uranium used in nuclear reactors uranium-235 contains 92 protons Another isotope uranium-238 contains how many electrons?
All the isotopes of uranium contains 92 protons and electrons but a different number of neutrons.
How does the atomic number relate to the number of protons in an atom?
Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)
What contains promethium?
The atom of promethium contain 61 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
Is 112Cd an isotope?
Yes 112Cd is an isotope of cadmium, called cadmium-112, which contains 48 protons and 64 neutrons. Cadmium-112 has a mass number of 112, which is the sum of the protons and neutrons in the atomic nuclei of the atoms of this isotope.
What are the number of protons in an every isotope?
There is no set number of protons in an isotope. The definition of an isotope is an atom that has the same number of protons but a different number of neutrons. Therefore, the answer to the question is; the number of protons in an isotope remain the same. To know the number of protons, look at the Periodic Table. The Atomic Number is the number of protons. Don't confuse that with Atomic Mass - To confirm, the Atomic Numbers for Hydrogen and Helium are 1 and 2.
What contains the element polonium?
Polonium contain 84 protons an electrons and a variable number of neutrons, depending on the isotope.
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.
An isotope of xenon has an atomic number of 54 and contains 77 neutrons. What is the mass number of the xenon isotope?
The atomic number of an element is the number of protons in its nucleus. Always. The mass number of an atom is the number of protons plus the number of neutrons in it. And that means an isotope of element 54 (xenon) that has 77 neutrons in its nucleus has a mass number of 54 + 77 or 131, and you'll have an atom of 131Xe. A link can be found below.
