WebThe electrons in the partially filled outermost shell (or shells) determine the chemical properties of the atom; it is called the valence shell. Each shell consists of one or more subshells, and each subshell consists of one or more atomic orbitals. WebExceptions to Electron Configuration - Concept. There are two main exceptions to electron configuration: chromium and copper. In these cases, a completely full or half full d sub-level is more stable than a …

WebExplanation for the correct option. (A) 1. The combining power or the combining capacity of an element is called its valency. Valency is simply equal to the number of electrons gained, lost, or shared by an atom of an element to achieve the nearest noble gas configuration. Octet rule is followed to find out the valency. WebSolution. Their shell are completely filled so they cannot undergo any chemical reaction so their electron gain enthalpy is almost Zero. They are very stable elements. If they gain electron they will become highly unstable. . Suggest Corrections. WebApr 13, 2024 · Source: byjus.com. Element with atomic number 15 on the periodic table is phosphorus (p).
