Introduction

Alkaline earth metals are a group of elements in the periodic table that are known for their unique properties and behaviors. One of the key characteristics of these metals is their tendency to form ions when they react with other elements. In this article, we will explore the behavior of alkaline earth metals when they form ions, and examine the correct answer to the question posed above.

What are Alkaline Earth Metals?

Alkaline earth metals are a group of elements in the periodic table that are located in Group 2. These elements are:

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

These elements are known for their ability to form ions when they react with other elements. In this article, we will focus on the behavior of these metals when they form ions.

How Do Alkaline Earth Metals Form Ions?

When alkaline earth metals react with other elements, they tend to lose electrons to form ions. This process is known as ionization. The number of electrons lost by an alkaline earth metal determines the charge of the ion it forms.

The Correct Answer

The correct answer to the question posed above is:

A. lose two electrons and adopt a +2 charge.

This is because alkaline earth metals tend to lose two electrons when they form ions. The loss of two electrons results in a +2 charge on the ion. This is a fundamental property of alkaline earth metals and is a key characteristic of these elements.

Why Do Alkaline Earth Metals Lose Two Electrons?

Alkaline earth metals lose two electrons because of their electronic configuration. These elements have two electrons in their outermost energy level, which are easily lost when they react with other elements. The loss of two electrons results in a +2 charge on the ion, which is a stable configuration for these elements.

Examples of Alkaline Earth Metals Forming Ions

There are several examples of alkaline earth metals forming ions. One of the most common examples is the reaction of magnesium (Mg) with oxygen (O2) to form magnesium oxide (MgO).

2Mg (s) + O2 (g) → 2MgO (s)

In this reaction, magnesium loses two electrons to form a +2 ion, which then reacts with oxygen to form magnesium oxide.

Conclusion

In conclusion, alkaline earth metals tend to lose two electrons when they form ions, resulting in a +2 charge on the ion. This is a fundamental property of these elements and is a key characteristic of their behavior. Understanding the behavior of alkaline earth metals in ion formation is essential for understanding their properties and behaviors.
