The atomic number of an atom is the number of protons or electrons present in an atom.
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.
Atomic number is the number of protons in the atomic nuclei of the atoms of an element.
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.
Different atomic numbers represent different elements.
There is not one: only single atoms or elements have atomic numbers.
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.
It is about the atomic numbers. The total of protons.
Isotopes describe atoms with different atomic masses due to varying numbers of neutrons.
they are called isotopes.
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.
it depends because isotopes have different nucleon numbers but their atomic number stays the same.
They have different numbers of neutrons.
