## Description

The "Table of Valences" Chrome extension provides a handy reference for the valences or oxidation numbers of chemical elements, designed especially for secondary-level students. The table organizes elements by groups based on their chemical nature and behavior, with color-coded groups to aid memorization through association. It also features interactive "learning cards" to reinforce understanding and retention of elemental valences.

This extension focuses on commonly used chemical elements necessary for formulating compounds in school chemistry. Additionally, it offers a practice section to help users memorize element symbols, names, and classifications, making learning both effective and engaging. Perfect for students and educators alike, it simplifies chemistry study and encourages play-based learning.
