About this app

Chemistry Note is a chemistry reference app that allows you to quickly find the information you need to study chemistry.

Select elements from the periodic table, perform necessary calculations, and review confusing concepts.

Chemistry Note ■ Periodic Table

· A periodic table classifying 118 elements by color

· Tap an element to view detailed information such as atomic number, atomic weight, electron configuration, and properties

· Atomic structure and electron configuration are displayed graphically for elements 1 through 20

· Remembers recently viewed elements for easy retrieval

· 'Element of the Day' provides one element every day

■ Chemistry Calculator

· Instantly calculates molecular weight by entering a chemical formula

· Calculates moles, concentration, and stoichiometry

· Displays not only the result but also the step-by-step solution process

■ Chemical Reactions

· Automatically adjusts coefficients when you enter a reaction equation

■ Ions & Compounds

· Select cations and anions to create chemical formulas and names for compounds

■ Molecular Structure

· Understand molecular structures by rotating molecules in 3D

■ Concept Notes & Quizzes

· Notes summarizing key concepts by unit

· Easy daily quizzes and error notes

· Use only when needed, without the pressure of having to solve them every day

■ Data Tables

· Ion tables, solubility tables, metal reactivity, indicators and pH, and frequently used Constant

■ For comfortable use

· Supports Dark Mode

· Does not require camera or personal information

Chemistry Note is a free app and contains advertisements.
