WebSep 1, 2024 · In this video we’ll use the Periodic table and a few simple rules to find the number of protons and electrons for the Chloride ion (Cl-). From the Periodic Table we … WebA chlorine atom has two electrons in its first shell, eight electrons in its second shell, and seven electrons in its outermost third shell. Only one more electron is needed to achieve an octet in chlorine’s valence shell. When a chlorine atom gains an electron, its outermost principal energy level achieves an octet.

WebJan 30, 2024 · Chlorine has seven valence electrons, so if it takes one it will have eight (an octet). Chlorine has the electron configuration of argon when it gains an electron. The octet rule could have been satisfied if chlorine gave up all seven of its valence electrons and sodium took them. WebActivity A: Ions Get the Gizmo ready: Click Reset.

WebNov 4, 2024 · Here is a table of element valences. Remember that an element's electron cloud will become more stable by filling, emptying, or half-filling the shell. Also, shells don't stack neatly one on top of another, so don't always assume an element's valence is determined by the number of electrons in its outer shell.
