Web23 de jul. de 2024 · Atoms can not exist independently. This is because atoms accept electrons or donate electrons to form stable octet fulfilled electronic configurations and this is only possible by formation of molecules. … But only inert gases already have octet fulfilled configurations so they can exist as atoms. By definition, any two atoms with an identical number of protons in their nuclei belong to the same chemical element. Atoms with equal numbers of protons but a different number of neutrons are different isotopes of the same element. For example, all hydrogen atoms admit exactly one proton, but isotopes exist with no neutrons (hydrogen-1, by far the most common form, also called protium), one neutron (deuterium), two neutrons (tritium) and more than two neutrons.
