Study Notes
Periodic Table of Elements
The Periodic Table of Elements is an organized list of chemical elements based on their properties. It shows how elements are related to each other by their repeating patterns in chemistry. The periodic table organizes all known elements by increasing atomic number (i.e., protons in an element's nucleus) which is also coincidentally their position in the table.
Atomic Number
Each element has its own specific atomic number, represented by the Arabic numeral following the chemical symbol. This atomic number denotes the number of protons present within the nucleus of any atom of that element. For example, hydrogen has an atomic number of 1, indicating there is one proton in every hydrogen atom.
Chemical Symbol
A chemical symbol is a unique character representing a particular chemical element. In the case of elements with multiple isotopes, each isotope may have a distinct symbol. These symbols were created from Latin, Greek, and Hebrew alphabets.
