WebThe classification of the elements into these groups is dependent on the extent to which the s, p, d and f orbitals are filled. (i) Inert gases . a) s- and p-orbitals of the outer most shell of these elements are completely filled. The outermost electronic configuration is ns 2 np 6. b) Helium is also inert gas but its electronic configuration ... WebSolution. The electronic configuration of magnesium (12) is: 2, 8, 2. The electronic configuration of calcium (20) is: 2, 8, 8, 2. Hence, magnesium (Mg) and calcium (Ca) are elements that have two electrons in their outermost shell. Suggest Corrections.

WebJun 8, 2024 · Figure 2.5. 1: Bohr diagrams: Bohr diagrams indicate how many electrons fill each principal shell. Group 18 elements (helium, neon, and argon are shown) have a full outer, or valence, shell. A full valence shell is the most stable electron configuration. Elements in other groups have partially-filled valence shells and gain or lose electrons … WebAn element can donate, accept, or share electrons with other elements to fill its outer shell and satisfy the octet rule. When an atom does not contain equal numbers of protons and electrons, it is called an ion. Because the number of electrons does not equal the number of protons, each ion has a net charge. Positive ions are formed by losing ... otto obermeyer
