Atom - A Simple & Powerful Chemistry Toolbox

Introducing Atom - the multifunctional science calculator, for students of chemistry, biology, mathematics, or just about anything.

With a built-in periodic table, you can look up important data -- such as molar mass, electronegativity, and electron configuration, among others -- for every element.

The units converter (updated regularly) allows you to quickly change to and from a variety of SI and non-SI units.

For any properly formatted chemical formula (just as you would find in textbooks), you can instantly solve for the molar mass and % composition by mass.

Input any DNA, mRNA, or amino acid sequence to gain relevant and pertinent data about that sequence, including but not limited to DNA and mRNA composition, complementary sequences, and protein molecular weight, hydrophobicity, and isoelectric point (pI).

Designed to be intuitive, responsive, and informative, Atom is a powerful scientific tool ready to be used for your next experiment, homework assignment, or curiosity.
