These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Similarly, magnesium (Mg) and aluminium (Al) have their valency as two and three, respectively as they have two and three electrons in their outermost shell. The electronic arrangement of the first 18 elements is listed below: The electrons present in the outermost shell of an atom are known as the valence electrons. Valence electrons are the highest energy electrons in an atom and are therefore the most reactive. The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. An outermost-shell, which had eight electrons possesses an octet and thus atoms would react to achieve an octet in the outermost shell. The significant role played by bitcoin for businesses! A look at the relationships and some of the tension with the shooter and the people the shooter interacted with. 6 Why do we use valence electrons to describe how atoms will bond? An electron is a negatively charged subatomic particle. According to this rule, atoms gain, loose or share electrons to achieve the stable configuration similar to the nearest noble gas.
