Electron shell - Wikipedia

In chemistry and atomic physics, an electron shell may be thought of as an orbit followed by electrons around an atom's nucleus. The closest shell to the nucleus is called the "1 shell" (also called the "K shell"), followed by the "2 shell" (or "L shell"), then the "3 shell" (or "M shell"), and so on farther and farther from the nucleus. The shells correspond to the principal quantum numbers (n = 1, 2, 3, 4 ...) or are labeled alphabetically with the letters used in X-ray notation (K, L, M, ...). A useful gui… Webthe ions have the electronic structure of a noble gas (group 0 element), with a full outer shell For elements in groups 1, 2 and 3, the number of electrons lost is the same as the … ship building contracts

How many electrons does it take to fill hydrogens outer shell?

WebThey are determined by the number of protons, neutrons, and electrons in the carbon nucleus and outer shells. Carbon has 6 protons and 6 electrons in its nucleus and outer shells. The number of neutrons in the nucleus of a carbon atom can vary, which results in different isotopes of the element. http://www.nat.vu.nl/~wimu/EDUC/MNW-lect-2.pdf WebTherefore, the valence electron of a hydrogen ion is zero. On the other hand, hydrogen donates an electron to form a bond or compound. Therefore, the valency of hydrogen … ship building education
