Atom calculator that helps determine subatomic composition, including the number of protons, neutrons, and electrons, using atomic number, mass number, and charge. It presents the atomic composition outputs directly on the tool page. ([calctool.org](https://www.calctool.org/physical-chemistry/atom))
This interactive isotope simulation guides users through calculating average atomic mass using isotope mass and abundance inputs. It functions as a hands-on calculator-style tool with immediate calculation feedback in a practice workspace. The simulation page is available online without a mandatory paid plan.
This mole calculator explains and applies Avogadro’s number for converting between moles and numbers of molecules/atoms. It includes formulas for moving between mass, moles, and particle counts in chemistry workflows. The calculator is available online without mandatory payment.
This Beer Lambert Law calculator computes the missing variable when three values are provided (extinction coefficient, path length, concentration, or absorbance). It is designed for spectroscopy workflows and includes scientific units commonly used in labs. The calculator is accessible online for free.
Our radioactive decay calculator will help you understand what radioactive decay is and how it is related to the activity of a substance.
This calculator computes any of the values in the half-life formula given the rest values. It also converts between half-life, mean lifetime, decay constant.
The ionic strength calculator is a convenient tool to help you calculate the ionic strength of a solution based on the ions present in it and their charge.
