About This Product
Students first find the neutral chlorine atom and the position for the missing outer electron, then watch the extra electron being added. The resulting chloride ion has one more electron than protons, which explains its single negative charge. The model supports lessons on valence electrons, electron transfer and ionic bonding. Besides buyers across India, the Formation of Chlorine Ion Model can be exported to institutions in Kuwait, Jamaica, Cambodia, Tanzania and Afghanistan.
Frequently Asked Questions
Q1. What is the difference between chlorine and chloride? Chlorine, Cl, is the neutral atom with seven outer-shell electrons. Chloride, Cl−, is the ion formed when that atom gains one electron, giving it a complete outer shell and a single negative charge.
