+# Element Creation
+
+Elements are the base of GT materials. Registering an element WILL NOT add any items.
+
+Elements can be created using `GTElements#createAndRegister` for ease of use. If you choose to declare them yourself, keep in mind you need to register your elements to `GTRegistries.ELEMENTS`
+
+Elements have the following parameters:
+
+2.  `long protons` -> Amount of Protons (use -1 if it is not an element that will get a material).
+3.  `long neutrons` -> Amount of Neutrons (use -1 if it is not an element that will get a material).
+4.  `long halfLifeSeconds` -> Amount of Half Life this Material has in Seconds. -1 for stable Materials
+5.  `String decayTo` -> String representing the Elements this element decays to. Separated by an '&' Character
+1.  `String name` -> Name of the Element
+6.  `String symbol` -> Symbol of the element. Used to represent the element in chemical formulas (eg. H for hydrogen, Zn for Zinc)
+7.  `boolean isIsotope` -> Is this element an isotope? (eg. Uranium-235 and Uranium-238)
+
+
+??? example
+    ```java
+    public static final Element Xz = GTElements.createAndRegister(16, 18, -1, null, "XYZ", "Xz", false); 
+    ```
+
+When a material will be created from this element, the above properties will affect the auto-generated recipes.
+
+
+!!! info "Mass number"
+    
+    The mass number of an element is the sum of its protons and neutrons. This affects the duration of some recipes, including wiremills and benders. A higher mass number usually  means the recipe takes longer to run. This affects any materials that are composed of the element as well
+
+## Registration
+Once your Element(s) are declared, they can be registered using IGTAddon#registerElements. See [here](../Setup.md#registering-your-content)
