WebThe atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74). Since the iodine is added as a 1− anion, the number of electrons is 54 ...

WebLet us determine the Lewis structures of SiH 4, CHO 2 −, NO +, and OF 2 as examples in following this procedure: Determine the total number of valence (outer shell) electrons in the molecule or ion. For a molecule, we add the number of valence electrons on each atom in the molecule: SiH4 Si: 4 valence electrons/atom×1 atom = 4 + H: 1 valence ... WebWhat symbol designates an ion that contains 8 protons and 10 electrons? A. O2- B. O2+ C. Ne D. B2+ A. O2- O2- indicates an ion of oxygen having two extra electrons. I.e., since an oxygen atom normally has 8 protons and 8 electrons, this ion has 10 electrons (-10 charge) and 8 protons (+8 charge) giving it a charge of -2 (-10 + 8 = -2).
