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 else can I help you with?
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 atomic number of an atom that contains 19 protons 19 electrons and 21 neutrons?
The atomic number by definition is the number of protons in the nucleus, therefore 19 in this instance. (The isotope effectively specified by the numbers given in the question is potassium-40, which is least commonly occurring natural isotope of potassium.)
An isotope of nitrogen could have more protons neutron electrons?
An isotope of nitrogen will always have 7 protons, as this defines the element. However, it can have a different number of neutrons, thus changing the mass number of the isotope. The number of electrons in an isotope is equal to the number of protons to maintain overall charge neutrality.
How many protons in a isotope of sodium with a mass number of 20?
All atoms of sodium contain 11 protons, since 11 is the atomic number of sodium.
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.
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.
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.
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)
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.
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
How much protons in 133Cs?
The element cesium (Cs) has an atomic number of 55, which means it has 55 protons in its nucleus, regardless of the isotope. The isotope 133Cs specifically indicates that it has 133 nucleons (protons + neutrons), but the number of protons remains the same at 55. Therefore, 133Cs contains 55 protons.
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.
What is the atomic number of an atom that contains 19 protons 19 electrons and 21 neutrons?
The atomic number by definition is the number of protons in the nucleus, therefore 19 in this instance. (The isotope effectively specified by the numbers given in the question is potassium-40, which is least commonly occurring natural isotope of potassium.)
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.
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.
