An interactive periodic table of all 118 elements with atomic masses, groups and electronegativity trends, plus a molar mass calculator with percentage composition and grams-to-moles conversion.
Use the guide alongside the working tool.
Open Periodic Table & Molar Mass Calculator →Pick the exam and document
Tap any element (or find it in the list) to see its atomic number, mass, group, period, block and electronegativity; colour the table by category, electronegativity or mass to see the trends.
Frame and clean up
Switch to Molar mass and type a formula such as H2SO4, Ca(OH)2 or CuSO4·5H2O.
Create and check
Read the molar mass and each element's share, convert grams to moles and particles, and copy the working.
Privacy and limits
Atomic masses are the IUPAC standard atomic weights rounded for school and college use; for elements with no stable isotope the mass number of the longest-lived isotope is shown in brackets. Formulas must use correct capitals (Co is cobalt, CO is carbon monoxide).
