WebA = N + Z Calculations. You already know how to find the mass number of an isotope by adding the protons and neutrons. We can state the relationship between protons, neutrons, and mass number with the following equation: atomic mass number = number of neutrons + atomic number (number of protons) Atomic mass number will be a whole number.
WebMar 11, 2024 · Find the atomic number of the element or isotope. The atomic number is the number of protons in an element, and never varies. For example, all hydrogen atoms, and only hydrogen atoms, have 1 proton. Sodium has an atomic number of 11 because its nucleus has 11 protons, while oxygen has an atomic number of 8 because its nucleus has … WebFrom the Table of Elements, we can see that mercury's atomic number is 80 and its atomic mass is 200.59. We'll need these numbers to get the information you want. The atomic number is the number of protons in an atom's nucleus, so we can tell right away that an atom of mercury contains 80 protons. Atoms, by definition, are electrically neutral.
WebSo the number of electrons is the same as the atomic number. However, it is possible to remove electrons and not change the identity of an element. These are called ions. The charge on the ion tells you the number of electrons. If the charge is positive, subtract that number from the atomic number to get the number of electrons. You have more ...
