Periodic Table: Chemistry Quiz

Learn chemistry the easy way with Periodic Table, an interactive periodic table of elements for students, teachers and anyone curious about science. Explore all 118 chemical elements, see how their properties change across the table, test yourself with chemistry quizzes and solve problems with built-in chemistry tools. It is quick to open and easy to use, so you can study whenever you have a few minutes. INTERACTIVE PERIODIC TABLE • All 118 elements in a clear, color-coded periodic table • Tap an element for a quick preview, tap again for full details • Element groups in color: alkali metals, alkaline earth metals, transition metals, lanthanides, actinides, metalloids, nonmetals, halogens and noble gases • Turn your phone sideways for a full-screen periodic table with pinch to zoom • Star your favorite elements to find them fast PERIODIC TRENDS See periodic trends at a glance with heat-map views of the table: • Electronegativity • Ionization energy • Electron affinity • Atomic mass • Density • Melting point and boiling point STATES OF MATTER EXPLORER Move the temperature slider and see which elements are solid, liquid or gas at that temperature. A simple way to understand melting and boiling points. ELEMENT DETAILS Each element page shows: • Atomic number, symbol and atomic mass • Electron configuration and electron shells • Group, period and block • Electronegativity, ionization energy and electron affinity • Density, melting point, boiling point and molar heat • Appearance, discovery and a short summary SEARCH AND COMPARE • Search elements by name, symbol or atomic number • Filter by element category, block, state of matter or starred elements • Compare two elements side by side and see how their properties differ CHEMISTRY QUIZ Practice and remember the elements with quick quiz rounds: • Element names and symbols • Atomic numbers • Element families and categories • States of matter, groups and periods • Periodic trends: which element has the highest value • Review mode to retry the elements you got wrong • Track your best scores and accuracy CHEMISTRY TOOLS • Molar mass calculator: enter a chemical formula to get its molar mass and atom counts • Chemical equation balancer: balance chemical reactions, with atom counts checked on both sides • Chemistry formula sheets: 36 key formulas for gas laws, mole concept, solutions, acids and bases, equilibrium, kinetics, thermodynamics and electrochemistry, each with variables and a worked example GREAT FOR • High school and college chemistry students • Exam revision and homework help • Teachers who want a quick classroom reference • Anyone who wants to learn the chemical elements WHY YOU WILL LIKE IT • No sign-up or account • Simple, clear layout that is quick to learn • Clean dark design that is easy on the eyes • Fast and lightweight The app is free to use and supported by ads.
