WebWhy atom has 2 electrons in its first shell? This first shell has only one subshell (labeled 1s) and can hold a maximum of 2 electrons. This is why there are two elements in the first row of the periodic table (H & He). Because the first shell can only hold a maximum of 2 electrons, the third electron must go into the second shell. Thanks.

WebMar 24, 2024 · Lower numbers correspond with the innermost energy level, while the seventh energy level is the outermost shell. Each shell contains one or more subshells, each of which also can contain only a maximum number of electrons, determined by the formula 4l + 2, where l is the quantum number of the subshell. WebThe innermost electron shell of an atom can hold up to _____ electrons.

What is the maximum number of electrons that the innermost …
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. The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form … The reason 2 is the magic number for the innermost shell lies in the laws of quant… And this is explained if we look at fluorine's valence shell (the second shell) electr… WebFor example, hydrogen has one electron which is located in the first (innermost) electron shell. This can be explained as an electron configuration and is designated as 1s1 (1 representing the electron shell, and s the subshell). The superscript 1 indicates one electron within the 1s orbital. songs with jupiter in the title
