A: Calcium is a group 2 element with two valence electrons. Therefore, it is very reactive and gives up electrons in chemical reactions. It is likely to react with an element with six valence electrons that “wants” to gain two electrons. This would be an element in group 6, such as oxygen.
Iron is constantly working to support life on Earth, from supplying plants with nutrients to serving as a key component of steel to carrying oxygen in your blood.
- Iron is the most common metal, its pure form corrodes quickly when exposed to humid air and high temperatures.
- it is abundant in the sun and stars.
- It contributes to the synthesis of chlorophyll in plants.
- It is a part of hemoglobin, a blood protein that transports oxygen from the lungs to the body's tissues in mammals.
- The majority of it is used to create steel, an iron and carbon alloy used in manufacturing.
- There are four main structural forms of iron, known as allotropic forms, in which atoms are bound in various ways.
These are few properties of iron that are unusual for metal.
