About Chemistry Tools
Chemistry apps built on one element data set: 118 elements with standard atomic weights, groups, blocks and Pauling electronegativity. The periodic table colours elements by category or property trends; the element explorer lists, filters and sorts them.
The molar mass calculator reads brackets, hydrates and ion charges and converts grams, moles and particles. The equation balancer solves for whole-number coefficients with exact fractions, including ionic and redox equations, and the configuration calculator shows orbital diagrams with measured exceptions such as chromium and copper.
