Welcome to our Chemistry Facts library. On this page you can access one of the largest collections of facts about the chemical elements on the periodic table. This is an excellent resource for students, teachers or anyone who wants to learn more about an element on the periodic table. We hope you find these facts about the elements informative and educational. You can begin to explore our chemistry facts library by scrolling down and choosing a section.
Our Chemistry Facts category is separated into different sections. Each of the below sections is about a specific chemical element. For example, we have a section about Hydrogen, Carbon and Oxygen. We're constantly adding new elements, if you can't find facts for a specific element then you should check back often. You can also contact us with your requests, and we'll add it to one of our future updates.
Each of the available chemistry facts sections is listed below, in order of their atomic number.
The periodic table of elements (periodic table) is a table that contains all the known chemical elements. The periodic table today contains 94 chemical elements that are natural and 24 that have only been synthesized in a lab, in a nuclear reactor, or in a nuclear explosion. Each chemical element on the periodic table is assigned an element name, an atomic number and its atomic weight. The atomic number is how many protons are in the nucleus of every atom of that element. The atomic weight is the total number of protons and neutrons in the atom.
The 94 naturally occurring elements on the periodic table belong to one of seven periods and one of four blocks. Periods are horizontal rows on the periodic table, so if a chemical element is on row three it's in period three. The blocks on the periodic table go from left to right in the following order s-block, f-block, d-block and b-block. The blocks on the periodic table represent the sequence in which the electron shells of the elements are filled.
The 94 naturally occurring elements on the periodic table belong to one of eighteen groups. The eighteen groups on the periodic table are the lithium group, beryllium group, scandium group, titanium group, vanadium group, chromium group, manganese group, iron group, cobalt group, nickel group, copper group, zinc group, boron group, carbon group, nitrogen group, oxygen group, fluorine group and helium group.
