alkaline metals

anonymous asked:

The mineral name for sodium is halite so calling a gemsona sodium is a bit strange since sodium is an alkaline metal that reacts violently to water so please do not let the goats lick the danger metal. You don't have to do anything with this information I just wanted you to know

@mingesu ur gemsona is a dangerous weapon

How to Calculate Oxidation Numbers Introduction

We’ll learn how to determine the oxidation numbers or oxidation states for a the elements in a chemical compound. The oxidation numbers tell us how electrons are divided up or shared between atoms in a chemical compound. The oxidation numbers also tell us how electrons move in an oxidation reduction (redox) reaction. There are a set a rules that we use to determine oxidation number. Group 1A elements (alkalai metals) always have an oxidation of +1. Group 2A elements (alkaline earth metals) always have an oxidation number of +2. Elements on their own have an oxidation number of 0, and monatomic ions have an oxidation number that is equal to the ionic charge.
