Developed the idea of electron shells

A useful guide when understanding electron shells in atoms is to note that each row on the conventional periodic table of elements represents an electron shell. Each shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, … See more 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 … See more Each shell is composed of one or more subshells, which are themselves composed of atomic orbitals. For example, the first (K) shell … See more Although it is sometimes stated that all the electrons in a shell have the same energy, this is an approximation.
