WebChlorine has 7 valence electrons. It needs one electron to make it stable at 8 electrons in its valence shells. This makes chlorine a Cl−1 anion. Ionic bonds form when the charges between the metal cation and non-metal anion are equal and opposite. This means that two Cl−1 anions will balance with one Ca+2 cation. WebElements in Groups 15,16 and 17, find it easier to gain electrons than lose them. For example, oxygen atoms gain two electrons to form O 2-ions. These have the same electron configuration as the noble gas neon. ... The chlorine atom, which starts with seven valence electrons, gains a single electron and becomes a negatively charged chlorine ion ...

7.4: Electron Configurations of Ions - Chemistry LibreTexts

WebChlorine (Cl) in its lowest energy state (called the ground state) has seven electrons in its outer shell. … Therefore, it tends to gain an electron to create an ion with 17 protons, 17 neutrons, and 18 electrons, giving it a net negative (–1) charge. It is now referred to as a chloride ion. What ions do CL form? WebChlorine has seven valence electrons. If chlorine gets one more, then chlorine would have an electron configuration like a noble gas, like that of argon. So chlorine will gain an … WebDec 3, 2010 · Study now. More answers.
