WebbThe shell closest to the nucleus, 1n, can hold two electrons, while the next shell, 2n, can hold eight, and the third shell, 3n, can hold up to eighteen. The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form … WebbEach hydrogen atom has one valence electron and is univalent. In chemistry and physics, a valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed. In a single covalent bond, a shared pair forms with both atoms in the bond each ...

Webb15 maj 2016 · This is why we say that the electron in the outermost shell has a higher (potential) energy than the inner most shells. So a less amount of energy is needed to … WebbThe valence shell meaning the outermost electron shell. Stability meaning that something is unreactive, that it won't engage in some kind of chemical reaction to reach a new … Webb16 juli 2024 · The valence shell is the outermost electron shell. An isolated atom's valence shell contain electrons with certain energy levels. When atoms are brought into close proximity, repulsion of their electrons causes the energy levels corresponding to the shells to split into discrete energy bands. btd4 on cool math games
