Webb5 feb. 2024 · Explanation: Number of protons always equal number of electron, but that’s the case with a neutral atom. This implies that it has same number of protons and electrons in it. It means it has same amount of positive and negative charge, which cancel each other, and the atom as a whole becomes electrically neutral. WebbSo A is the mass number, which is equal to the number of protons, that's the atomic number which we symbolized by Z, plus the number of neutrons. So A is equal to Z plus N. And for protium, let's look at protium here. So in the nucleus there's only one proton and zero neutrons, so one plus zero gives us a mass number of one.

Why must the number of protons and electrons be equal?

The atomic number or nuclear charge number (symbol Z) of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei, this is equal to the proton number (np) or the number of protons found in the nucleus of every atom of that element. The atomic number can be used to uniquely identify ordinary chemical elements. In an ordinary uncharged atom, the atomic number is also equal to the number of electrons. Webb20 juli 2024 · In the terminology of NMR, all three H a protons are chemically equivalent to each other, as are all three H b protons.

If more protons are present, the ion is positive and is known as a cation; if more electrons are present, the ion is negative and referred to as an anion. Ions are highly reactive species. WebbHow many protons and neutrons does it contain and what is its charge? We figured out its charge. We know the protons. By definition platinum has 78 protons. But what about its neutrons? Well protons plus neutrons is going to be equal to our mass number. It's going to be equal to 195. So we have 78 protons plus I'll say N for neutrons is equal ... the bad thing lyrics arctic monkeys
