What does it mean if two atoms are isotopes?

If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.


What does an element's atomic number stand for?

Atomic number is the number of protons in the atomic nuclei of the atoms of an element.


What are atoms that have the same atomic number but different neutron numbers?

Atoms that have the same atomic number but different neutron numbers are known as isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in their atomic mass.


A difference in the atomic number of atoms means the atoms are of same or diffierent elements?

Different atomic numbers represent different elements.


What is the atomic number for a Hershey bar?

There is not one: only single atoms or elements have atomic numbers.


Do some atoms have more or fewer protons than will other atoms of the same element?

No. The atomic number of an element is determined by its number of protons. If two atoms have different numbers of protons, they have different atomic numbers and are different elements.


What tells you the number of Atoms in of an element?

It is about the atomic numbers. The total of protons.


Which term describes atoms with different atomic masses due to varying numbers of neutrons?

Isotopes describe atoms with different atomic masses due to varying numbers of neutrons.


What would you call atoms having some atomic numbers but different mass numbers?

they are called isotopes.


Do isotopes have the same atomic number and different mass numbers?

Yes. Isotopes have the same atomic number because all of their atoms have the same number of protons. They have different mass numbers because their atoms have different numbers of neutrons, and mass number is the sum of the numbers of protons and neutrons.


Atomic mass is an atoms number of what?

it depends because isotopes have different nucleon numbers but their atomic number stays the same.


How can different atoms of the same element have the same atomic number but can have different mass numbers?

They have different numbers of neutrons.
