Strontium: Number Of Valence Electrons: Analyzing The Outermost Electron Shell Of Strontium

Posted by on Mar 18, 2023 in Uncategorized |

Do you ever wonder why certain elements react with others to create compounds? It all comes down to their valence electrons. Valence electrons are the outermost electrons in an atom’s electron shell, and they determine an element’s chemical behavior. Understanding the number of valence electrons an element has can help predict how it will interact with other elements in chemical reactions.

In this article, we will be focusing on strontium and analyzing its outermost electron shell. Strontium is a chemical element with the atomic number 38, and it is a soft, silvery metal. Its atomic structure includes two electrons in the first energy level, eight electrons in the second energy level, and eighteen electrons in the third energy level. By understanding its valence electrons, we can predict how strontium will interact with other elements in chemical reactions and its properties as a metal.

The Importance of Valence Electrons in Chemistry

Valence electrons are crucial in understanding the chemistry of elements. These are the electrons located in the outermost energy level of an atom and are responsible for determining the chemical properties of an element. The number of valence electrons in an atom is directly related to its reactivity and bonding behavior. In general, elements with fewer valence electrons tend to be more reactive and readily form chemical bonds with other elements to achieve a stable electron configuration.

The properties of an element are largely determined by its valence electrons. For example, the noble gases, which have a full outermost energy level, are very stable and non-reactive. On the other hand, alkali metals such as sodium and potassium have only one valence electron, making them highly reactive and prone to form ionic bonds with other elements. Understanding the number and behavior of valence electrons is essential in predicting the chemical behavior of an element. Now, let’s delve into the analysis of strontium’s outermost electron shell.

Analyzing Strontium’s Outermost Electron Shell

So, what we’re looking at here is the most important and outer layer of electrons in strontium. Strontium has an electron configuration of [Kr] 5s^2, meaning it has two valence electrons in its outermost electron shell. These valence electrons play a crucial role in determining the chemical properties of strontium and how it reacts with other elements.

Because strontium has two valence electrons, it tends to lose these electrons to form a stable 2+ ion. This makes strontium highly reactive and prone to forming chemical compounds with other elements, especially those with a high affinity for electrons. Strontium’s reactivity also makes it useful in various industrial and scientific applications, such as in pyrotechnics and medical imaging. Overall, analyzing the outermost electron shell of strontium provides insight into its chemical properties and how it interacts with other elements in chemical reactions.


In conclusion, understanding the number of valence electrons in an atom is crucial in predicting its chemical behavior and properties. For strontium, the outermost electron shell contains two valence electrons, which makes it highly reactive with other elements. This reactivity is especially useful in industries such as pyrotechnics, where strontium is used to produce a bright red color in fireworks.

Furthermore, the analysis of strontium’s outermost electron shell also helps in determining its chemical bonding behavior. Strontium has a tendency to form ionic bonds with elements that have fewer valence electrons, such as chlorine and oxygen. This behavior is due to the fact that strontium can easily lose its two valence electrons to form a stable cation. Overall, the study of valence electrons and their role in chemical reactions is essential in understanding the behavior of atoms and molecules in the world around us.
