Explanation
- Connect the valence electron count to the outermost energy level of strontium.
Explanation
The number of valence electrons in an element is directly related to the outermost energy level, or electron shell, of its atoms. In the case of strontium, its valence electrons are found in the outermost electron shell, which is the fifth shell. This outermost shell can hold a maximum of eight electrons, so strontium’s two valence electrons make up half of this capacity.
The arrangement of electrons in an atom’s outermost shell determines the element’s chemical properties. For strontium, with two valence electrons, the outermost shell is half-filled. This stable half-filled configuration makes strontium less likely to lose or gain electrons, resulting in a neutral charge. Therefore, strontium typically forms positive ions by losing its two loosely held valence electrons to achieve a stable, filled outermost shell.
