Atomic number and mass number - Atomic structure

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. WebFinding the Number of Neutrons. The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. Both of these numbers can be found on the periodic table. The atomic number is listed above the symbol of the element whereas the mass number is placed below. Let’s keep using oxygen as our example. WebFor an ion: Atomic number = Number of protons = Number of electrons + Charge on atom Example: A sodium atom has 11 protons and 11 electrons which also denotes It has 11 positive charges and 11 negative charges. So, its atomic number can be calculated as = Number of protons = Number of electrons = 11. brian monton hart mich
