WebMar 24, 2024 · Therefore, it needs two electrons to complete its octet and obtain the noble gas configuration of argon. Hence it adds two electrons to its atom to form the sulfide ion and it obtains -2 charge so, it is written as ( S 2 − ). Some of the ions are N a + because one electrons is removed, M g 2 + because two electrons are removed, A l 3 ... WebJan 2, 2024 · Potassium (K +) has a 1- charge, while chlorine (Cl-) has a 1- charge. Note that you do not ever write a subscript of 1. If the charges on the cation and the anion are not equal, add subscripts as needed to the ions to balance the charge. The total charge for each ion is the subscript multiplied by the charge. Adjust the subscripts to balance ... nordstrom rack marin county
