Answer and Explanation: An atom that has more protons than electrons is called a cation. Ions are charged atoms or combinations of atoms. When an atom loses one or more... Learn more about this topic: Cation | Definition, Formation & Examples ...
In all atoms, the number of protons and the number of electrons is always the same. So nitrogen has 7 protons and 7 electrons, calcium has 20 protons and 20 electrons, and tin has 50 protons and 50 electrons. The number of neutrons is very roughly the same as the number of protons, ...
Therefore oxygen has8 electrons. You will find that the atomic weight of oxygen is about 16. How many protons neutrons and electrons does oxygen-16 contain? Naturally occurring oxygen is composed of three stable isotopes, 16O, 17O, and 18O, with 16O being the most abundant (99.762% natura...
