WebThe shell closest to the nucleus, 1n, can hold two electrons, while the next shell, 2n, can hold eight, and the third shell, 3n, can hold up to eighteen. The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. WebThus, all the valence electrons of Ca 2+ ion are the 8 lone pair electrons present on it. Lone pair electron calculation for Ca2+ lewis structure is given below: Lone pair electrons on …
