Chemical Element Converter

Use this free Chemical Element Name and Symbol Converter to find the chemical symbol, element name, atomic number, and approximate atomic mass of any of the 118 recognized chemical elements. Enter a name like Iron, a symbol like Fe, or an atomic number like 26 to find the information instantly.

How to Use the Chemical Element Converter

Using this tool is simple. Enter a chemical element’s name, symbol, or atomic number in the search box. The matching element details will appear automatically. You can also select a suggested result or copy the element name, symbol, or complete details for your notes.

For example, entering Iron displays the symbol Fe, while entering Fe identifies the element as Iron. You can use the same method to look up other elements, such as Oxygen, Gold, Silver, and Carbon.

Chemical Element Names and Symbols Table

The periodic table contains 118 officially recognized chemical elements. Each element has a unique chemical symbol, usually made up of one or two letters. The first letter is always capitalized, and the second letter, when present, is lowercase.

Here are some commonly used chemical elements and their symbols.

Atomic Number	Element Name	Chemical Symbol	Approximate Atomic Mass (u)
1	Hydrogen	H	1.008
2	Helium	He	4.003
3	Lithium	Li	6.940
5	Boron	B	10.810
6	Carbon	C	12.011
7	Nitrogen	N	14.007
8	Oxygen	O	15.999
11	Sodium	Na	22.990
12	Magnesium	Mg	24.305
13	Aluminium	Al	26.982
17	Chlorine	Cl	35.450
19	Potassium	K	39.098
20	Calcium	Ca	40.078
26	Iron	Fe	55.845
29	Copper	Cu	63.546
30	Zinc	Zn	65.380
47	Silver	Ag	107.868
50	Tin	Sn	118.710
53	Iodine	I	126.904
79	Gold	Au	196.967
80	Mercury	Hg	200.592
82	Lead	Pb	207.2

Note: Atomic masses are approximate reference values. The standard atomic weight of some elements varies with isotopic composition, while bracketed values for certain radioactive elements refer to a mass number rather than a standard atomic weight.

Why Do Chemical Elements Have Different Symbols?

Chemical symbols provide a short, internationally recognized way to identify elements in scientific formulas and equations. Some symbols come from the element’s English name, such as O for Oxygen and C for Carbon. Others come from older Latin names. For example, Fe comes from ferrum, the Latin name for Iron, while Au comes from aurum, the Latin name for Gold.

Symbols are case-sensitive in chemical notation. For example, Co represents Cobalt, whereas CO is the chemical formula for carbon monoxide. Using the correct capitalization helps avoid confusion when reading formulas.

Who Can Use This Tool?

This converter is useful for students, teachers, science enthusiasts, and anyone who needs to identify an element quickly. It can help with chemistry homework, revision, understanding chemical formulas, and checking element symbols while studying the periodic table.

Frequently Asked Questions

What is the chemical symbol for Iron?

The chemical symbol for Iron is Fe. Its atomic number is 26.

How many chemical elements are there?

There are 118 officially recognized chemical elements, from Hydrogen (H) to Oganesson (Og).
