WebJul 14, 2024 · Updated on July 14, 2024. In chemistry, the principal energy level of an electron refers to the shell or orbital in which the electron is located relative to the atom's nucleus. This level is denoted by the principal quantum number n. The first element in a period of the periodic table introduces a new principal energy level. 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 usef… WebThe 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.
