Cl-18 What is the … WebThe atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom.
WebIf the charge is +1 or −1, the convention is to write + or − (without the 1) as a superscript on the right. If the charge is +2, +3, −2, or −3, we write 2+, 3+, 2−, or 3− as the superscripts. Examples are below. Because all of the isotopes of an element have the same atomic number, the atomic number is often left off the isotope ...
Web2 Sep 2024 · The nuclear symbol of an isotope indicates the number of protons and neutrons in an atom of the element. It does not indicate the number of electrons. The number of neutrons is not stated. Instead, you have to figure it out based on the number of protons or atomic number.
