- Periodic table - Wikipedia
The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups") An icon of chemistry, the periodic table is widely used in physics and other sciences
- List of chemical elements - Periodic Table
Here's a list of all of the chemical elements of the periodic table ordered by increasing atomic number Click on the column header to sort the table by that column or click on an element name to get detailed facts about the element

Interactive periodic table with element scarcity (SRI), discovery dates, melting and boiling points, group, block and period information
- Element List – Element Names, Symbols, and Atomic Numbers
This element list includes the names, symbols, and atomic numbers of all 118 chemical elements, arranged in order of increasing atomic number The atomic number is the number of protons in an atom of that element

There are 118 elements on the periodic table The elements are arranged in order of increasing atomic number, which is the number of protons in that atom’s nucleus Hydrogen, the element with the lowest atomic number, has 1 proton; oganesson, the element with the highest atomic number, has 118
- Periodic Table of Elements - American Chemical Society
The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic number
- PERIODIC TABLE OF THE ELEMENTS
The atomic masses (bottom) of stable elements are weighted by isotopic abundances in the Earth’s surface Atomic masses are relative to the mass of 12C, defined to be exactly 12 unified atomic mass units (u)
