How to read the periodic table

The horizontal rows are called periods — there are 7. An element's period number equals the number of electron shells in its atom.
The vertical columns are called groups — there are 18. Elements in the same group have similar chemical properties.
The atomic number is the number of protons in the nucleus, which equals the number of electrons in a neutral atom.
Lanthanides and actinides are shown in two separate rows below the main table.

The periodic table in the Nalukh chem app

In the app, the periodic table is free and open without an account. It shows each element's atom as an animated Bohr model.

The periodic table quiz helps you learn atomic numbers, symbols and atomic masses — pick a range from the first 10 elements up to all 118.
