Atom

The atom calculator finds the number of protons, neutrons, and electrons in an atom.

Atomic mass

The atomic mass calculator takes the number of protons and neutrons in an atom and displays the atomic mass in atomic mass units and kilograms.

Average atomic mass

The average atomic mass calculator determines the average atomic mass of elements based on the isotopic mass and their natural abundance.

Bond order

In this bond order calculator we will show you how to find the bond order using Lewis structures, or a formula derived from the molecular orbital theory.
