What else can I help you with?
What is it called when they have same atomic number but different mass?
They are called isotopes of the same element
What are atoms with same atomic mass but different atomic numbers called?
Isotopes. The isotope has the same number of protons and electrons as the regular atom, but has more (or sometimes less) neutrons, and therefore its atomic mass is more (or less, depending on whether the neutrons have increased or decreased).
What are atoms that have the same number but different weights?
Atoms that have the same number of protons but different weights are called isotopes. Isotopes of an element have the same atomic number (number of protons), but a different atomic mass (sum of protons and neutrons) due to varying numbers of neutrons.
What is the difference between a nuclide and an isotope?
An isotope is an element that has the same number of protons and a different number of neutrons, whereas a nuclide is a specifically defined isotope. Quite literally, they refer to the exact same atom, but the difference lies in the definition. Nuclides are defined by many different aspects, such as half life, mode of decay, percent abundance, and so on. The Chart of the Nuclides is a very extensive reference for the characteristics of over 3000 different isotopes. The term isotope is merely a way of differentiating between an atom that is the same element (same number of protons) but has varying numbers of neutrons.
What do you call atoms of the same element with different atomic masses?
They are called isotopes. They have different mass nmbers because they have a different number of neutrons.
What is a heavy nuclides?
Heavy nuclides are atoms that have a high atomic number and are typically found in the lower region of the periodic table, such as elements like lead, uranium, and thorium. These nuclides often have a high mass and can be unstable, leading to radioactive decay.
How many stable nuclides exist for elements that have and atomic number above 83?
All isotopes of all elements with atomic number similar or greater than 84 are radioactive, and don't have stable nuclei.
Atoms that have the same atomic numbers but different atomic weights are called what?
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
What is it called when they have same atomic number but different mass?
They are called isotopes of the same element
What is the number of protons in the neucleus called?
the answer is that it is called a atomic number.
Which refers to atoms with the same atomic number but different atomic masses?
They are called isotopes. eg we have different isotopes of carbon
What atoms has different masses but the same atomic number?
Isotopes of an element have different masses but the same atomic number. Isotopes have the same number of protons and electrons but different numbers of neutrons in their nuclei.
Atoms of the same atomic are called what?
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
What do you called in an element having the same atomic number but different atomic masses?
Isotopes. eg U235 and U238. Both Uranium, atomic number 92, bur different isotopes.
What are atoms with same atomic mass but different atomic numbers called?
Isotopes. The isotope has the same number of protons and electrons as the regular atom, but has more (or sometimes less) neutrons, and therefore its atomic mass is more (or less, depending on whether the neutrons have increased or decreased).
What are the atoms called then they have the same atomic number but different mass numbers?
They are called as isotopes in which mass number differ by emmision of radiation
What are atoms that have the same number but different weights?
Atoms that have the same number of protons but different weights are called isotopes. Isotopes of an element have the same atomic number (number of protons), but a different atomic mass (sum of protons and neutrons) due to varying numbers of neutrons.
