Considering all the three above mentioned principles is the best approach for deciphering the electronic configuration of any element. For example, the total number of electrons in an oxygen atom is 8. The first step is to fill the lowest energy shell 1s with two electrons. The rest six electrons are distributed in 2s and 2p orbitals. 2s orbital will have two electrons, and 2p orbital will have four electrons. According to Neil Bohr, all the members of the same group of the Periodic table have a similar electronic configuration. Therefore, it also stands true for all the members of group 16, and the electronic configuration of oxygen follows the pattern of the general electronic configuration of group 16 elements, which is ns2 np4.
Since the noble gas is considered to have a complete electronic shell, the electronic configuration of most elements is represented in terms of its nearest noble gas.
It is important to note that the electronic configuration of any elements determines its chemical properties. Group 16 electron configuration indicates that its members of Group 16 have six elements in its valence shell, and therefore require two elements to complete the octet valency. Therefore all the elements of group 16 are negatively charged since it can receive two electrons from other elements. These anions can interact with positively charged cations that can donate electrons so that their octet is also completed along with these anions. For example, oxygen receives two electrons, one from each hydrogen atom to form water. Sulfur receives two electrons, one from each hydrogen atom to form hydrogen sulfide gas.
1. What is the General Electronic Configuration of Group 16 Elements?
The general electronic configuration of group 16 elements is ns2 np4.
2. What is the Number of Electrons Present in the Valence Shell of Group 16 Elements?
Six electrons are present in the valence shell of group 16 elements.
3. What are the Principles Followed to Define Electronic Configuration?
Pauli’s exclusion principle, Hund’s rule, and Aufbau’s principles are followed to determine the electronic configuration of any elements.
4. What is the Radioactive Element in Group 16?
Polonium is a radioactive element in group 16.
5. Why are Elements of Group 16 Negatively Charged?
Since all the elements of group 16 have six electrons in their valence shell, they can accept two electrons to complete the octet valency. Therefore, these elements are negatively charged.
