Kalzium is a full-featured chemistry application for KDE 5, including a Periodic Table of Elements, chemical reference, chemical equation solver, and 3D molecule viewer.
Key Features
- Visualize the Periodic Table of the Elements by groups, blocks, and families.
- Plot data for a range of elements for properties like the boiling point or the atomic mass.
- Calculate the molecular mass of molecules.
- Show the isotopes of the elements.
- R/S Phrases, also known as Risk and Safety Statements, R/S statements, R/S numbers, and R/S sentences, is a system of hazard codes and phrases for labeling dangerous chemicals and compounds.
- Equation solver enables the user to solve chemical equations.
- Timeline – Go back in time and see what elements were known at a given date.
