Also, the more active the metal, the more vigorously does it react with water. Thus potassium and sodium react vigorously even with cold water, while magnesium reacts only with steam. A burning piece of magnesium continues to burn vigorously, when brought in contact with steam.
Metals and Non-Metals | Brilliant Math & Science Wiki
The periodic table can be broadly segregated into two types of elements, commonly referred to as metals and non-metals. Each of these elements have varying properties and can be found in a wide variety of places, such as bridges, buildings, roads, electric cables, cars, aircraft, mobile phones, and laptops, as well as in the oxygen we breathe and the carbon dioxide we exhale. Over the course

The electron in their most outward electron shell are in the s-orbital.[1] Elements in the s- are in the first two periodic table groups.[2] The elements in group one are called the alkali metals. The elements in group two are
Preventing Metal Corrosion with Metalworking Fluids : …
By definition, corrosion is the partial or complete wearing away, dissolving or softening of any metal substance by chemical action. The term 'rust' is often misapplied or misused, as it applies only to iron and steel. The term 'corrosion,' however, is all inclusive, in that it not only applies to ferrous metals but also to non-ferrous metals. The following discusses the causes
