In a atom the number of electrons are equal
WebWhen a Ca atom loses both of its valence electrons, the result is a cation with 18 electrons, a 2+ charge, and an electron configuration of 1 s2 2 s2 2 p6 3 s2 3 p6. The Ca 2+ ion is therefore isoelectronic with the noble gas Ar. For groups 13–17, the group numbers exceed the number of valence electrons by 10 (accounting for the possibility ...

WebJan 27, 2024 · In a neutral atom, the number of both electrons and protons are equal. Hence, Atomic number \ (=\) number of protons \ (=\) number of electrons Atoms are neutral; hence, the number of electrons is equal to the number of protons. For example, the atomic number of manganese is \ (25\). Web2. Atoms in monatomic (i.e., one-atom) ions are assigned an oxidation number equal to their charge. Oxidation numbers are usually written with the sign first, then the magnitude, which differentiates them from charges. 3. In compounds, fluorine is assigned a −1 oxidation number; oxygen is usually assigned a −2 oxidation number (except in peroxide …
