  1. Each element has a number. Hydrogen is 1, copper is 29, polonium is 84, and so forth. This number corresponds to the quantity of protons in the nucleus. Altering this number changes the atom’s element.

    Interestingly, this isn’t strictly true. Hydrogen-4.1 has two protons, two neutrons, one muon, and one electron. A muon is a negatively charged particle with about 1/10 the weight of a proton or neutron (hence 4.1). Because it’s much heavier than an electron, it tends to orbit much closer to the nucleus and bind more tightly, so effectively the nucleus of hydrogen-4.1 has a charge of +1, and it has the chemical properties of hydrogen rather than helium.Report
