WebDec 30, 2024 · In ClO2- molecule, chlorine is the central atom and it needs 8 electrons around to complete the octet. As you see in the structure of the 4th step, chlorine already sharing 4 electrons with the help of two single bonds connected to oxygen atoms. So, just put the 4 leftover valence electrons on chlorine and complete its octet.

WebJul 4, 2024 · Since each chlorine atom gained an electron, they each have 17 protons and 18 electrons. This makes each chloride a negative ion with a charge of −1. Oppositely charged ions attract each other, forming an ionic bond. How many electrons does Cu2+ have? There are 27 electrons in the Cu2+ ion. As copper has an atomic number of 29, it also will ... WebDec 23, 2016 · Chlorine has 7 valence eletrons Explanation: You know this by looking at the groups (vertical) of the periodic table. Chlorine is in the Halogens (Group 17) so it has a -1 charge (meaning 7 valence electrons; one short of 8, which makes a full octet) Answer link WebHow many electrons does a chlorine ion have? 18 electrons Again, it is more energy-efficient for chlorine to gain one electron than to lose seven. Therefore, it tends to gain an … chime bank text alerts
