Alkaline Earth Metals Reactions, Uses, Properties

Alkaline earth metals (Be,Mg,Ca,Sr,Ba,Ra) have similar and different characteristics to alkali metals. Alkaline earth metals are reactive but less than alkali metals. Here we discuss about occurrence, reactions, physical properties of alkaline earth metals.

4 Types of Metal That Are Corrosion Resistant or Don''t Rust

2018/10/3· Not all metals contain iron, but they can corrode or tarnish in other oxidizing reactions. To prevent oxidation and breakdown of metal products, such as handrails, tanks, appliances, roofing or siding, you can choose metals that are “rust-proof” or more accurately, “corrosion-proof.”

How Does Zinc React With Hydrochloric Acid? | Healthfully

A metal''s ability to react with HCl depends upon the metal''s so-called activity, where metals with high activity react with HCl. Metallic zinc''s activity is high enough to allow it to react with HCl, which produces H2 gas and the compound zinc chloride, or ZnCl2, explains Dr. Martin Silberberg in his book “Chemistry: The Molecular Nature of Matter and Change. 1 "

IGCSE Study Guides, Revision & Notes: Metals

Some metals such as potassium and sodium are so reactive they will react vigorously with cold water to form metal hydroxides and hydrogen gas. For the moderately reactive metals they will only react with steam to produce the appropriate oxide and hydrogen gas.
