A neutron is slightly more massive than a proton (see below) and has about the same diameter. Table of Contents What is oxygen? Thus, "9p + 9n 0, 9e + " is notthe number of protons, neutrons, and electrons present in the oxygen isotope. A neutronis one of thesubatomic particlesthat make up matter. . The slighty greater mass of 18O12.5 percent more than 16Oresults in differentiation of the isotopes in the Earths atmosphere and hydrosphere. The mass of an electron is only about \(\textstyle\frac1{2000}\) the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. This temperature-based skew effect means that the oxygen isotope make-up of shells would not precisely match the make-up of the ocean water in which they grew. Electrons, protons, and neutrons are located in the atom as permanent particles. The mass of the electron is often ignored because this mass is too small. Oxygen atoms with 8 neutrons would have a mass number of 16 (8 p + + 8 n 0 ), meaning they would have a mass of about 16 amu. This means that oxygen atoms have 8 protons. In the periodic table, the elements are listed in order of increasing atomic number Z. It should be noted that all of these decay pathways may be accompanied bythe subsequent emission ofgamma radiation. Hotspot. Oxygen.
