Ions with 18 electrons

Write the symbol of a cation from group 1A with 18 electrons.

An ion is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons is unequal to its total number of protons. WebA - Yes, because the Octet Rule says stable atoms have 8 electrons. B - No, because the atoms have only 6 valence electrons, but need 8 for stability. C - Yes, because oxygen …
