Elements chart atomic mass of oxygen
WebAn oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999. The atomic number tells you how many protons are in the atom's nucleus. This identifies the atom. For example, if the atomic number were 7, then the atom would be nitrogen, with 7 protons … WebThis is a list of the 118 chemical elements that have been identified as of 2024. A chemical element, often simply called an element, is a type of atom which has the same number of protons in its atomic nucleus (i.e., the same atomic number, or Z ). [1]
