Understanding Alkaline Earth Metals: A Key Concept in Chemistry

Introduction

Alkaline earth metals are a group of elements in the periodic table that are known for their unique properties and characteristics. These metals are located in Group 2 of the periodic table and are characterized by their ability to readily lose two electrons to form a positive ion. In this article, we will explore the concept of alkaline earth metals and identify which of the given options is a member of this group.

What are Alkaline Earth Metals?

Alkaline earth metals are a series of elements that are located in Group 2 of the periodic table. These elements are characterized by their ability to readily lose two electrons to form a positive ion. The alkaline earth metals are:

  • Beryllium (Be)
  • Magnesium (Mg)
  • Calcium (Ca)
  • Strontium (Sr)
  • Barium (Ba)
  • Radium (Ra)

These elements are known for their ability to form compounds with a +2 charge, which is a result of the loss of two electrons from the outermost energy level.

Properties of Alkaline Earth Metals

Alkaline earth metals have several unique properties that distinguish them from other elements. Some of the key properties of alkaline earth metals include:

  • High melting and boiling points: Alkaline earth metals have high melting and boiling points due to the strong electrostatic forces between the positively charged ions and the negatively charged electrons.
  • High reactivity: Alkaline earth metals are highly reactive and readily lose two electrons to form a positive ion.
  • Ability to form compounds with a +2 charge: Alkaline earth metals are able to form compounds with a +2 charge, which is a result of the loss of two electrons from the outermost energy level.
  • Ability to form compounds with a wide range of anions: Alkaline earth metals are able to form compounds with a wide range of anions, including halides, oxides, and carbonates.

Identifying the Alkaline Earth Metal

Now that we have a better understanding of what alkaline earth metals are and their properties, let's look at the given options and identify which one is a member of this group.

  • Option 1: Cd (Cadmium) - Cadmium is a transition metal and is not an alkaline earth metal.
  • Option 2: Cl (Chlorine) - Chlorine is a halogen and is not an alkaline earth metal.
  • Option 3: None of these - This option suggests that none of the given options are alkaline earth metals.
  • Option 4: Cr (Chromium) - Chromium is a transition metal and is not an alkaline earth metal.
  • Option 5: Ca (Calcium) - Calcium is an alkaline earth metal and is a member of Group 2 of the periodic table.

Conclusion

In conclusion, the correct answer is Option 5: Ca (Calcium). Calcium is an alkaline earth metal and is a member of Group 2 of the periodic table. It is characterized by its ability to readily lose two electrons to form a positive ion and is able to form compounds with a wide range of anions.
