It is called an Isotope.... C12, C13, C14 is a classical example
The key difference that causes atoms of one element to differ from all other elements is the number of protons in their nucleus. This number, known as the atomic number, determines the element's specific properties.
They are called isotopes,
Atoms that have different masses but the same number of protons are called isotopes. Isotopes of an element have the same number of protons, which determines the element's identity, but a different number of neutrons, leading to variations in atomic mass.
The number of protons in a nucleus is called the proton number, or atomic number. It is what defines which element we have.
The sum of protons and neutrons in an atom is called mass number.
Those are called Isotopes.
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
Isotopes.
By number of protons/electrons.
Atoms containing the same number of protons but different numbers of neutrons are called isotopes. Isotopes have the same atomic number (number of protons) but differ in atomic mass due to the varying number of neutrons.
Two atoms that have the same number of protons are called isotopes.
Two atoms that have the same number of protons are called isotopes.
The essential difference is the number of protons.
Sodium has 11 positively charged protons. (All atoms have positively charged protons, though they differ in hte number of protons).
Atoms of different elements differ in their number of protons, which determines the element's identity. Each element has a unique number of protons in its nucleus, leading to distinct chemical properties. Differences in the number of neutrons and electrons can result in isotopes and ions of the same element.
