Reactivity Series Flashcards | Quizlet

One method of preventing rust is by covering Iron/Steel in a more reactive metal, such as Magnesium or Zinc. This more reactive metal with react with oxygen first, protecting the Iron or Steel below. The metal must be more reactive than Iron. It is called sacial protection, because the magnesium or zinc is saced to protect the iron.

Metals | Boundless Chemistry - Lumen Learning

Magnesium and calcium are ubiquitous and essential to all known living organisms. Key Terms. Alkaline earth metals: A group of chemical elements in the periodic table with similar properties: shiny, silvery-white, somewhat reactive at standard temperature and pressure. They readily lose their two outermost electrons to form ions with charge +2.

Stability of calcium carbonate and magnesium …

Since alkali carbonates dissolve too easily in water, alkaline earth metals are more suitable for carbonation. Several other metal oxide bearing compounds can also be carbonated, but most of them are too rare or valuable, such as iron. Magnesium and calcium are the most common alkaline earth metals.

What elements reacts rapidly when dropped in water?

Calcium reacts more easily with water than does magnesium, because calcium donates electrons to other elements more readily than magnesium, as expected for a larger atom in the same periodic table
