The periodic table By convention elements are organized in the periodic table a structure that captures important patterns in their behavior Devised by Russian chemist Dmitri Mendeleev 1834 1907 in 1869 the table places elements into columns groups and rows periods that share certain properties 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, the third shell can hold ...

How Many Electrons Can The Third Shell Hold1 to 20: Predicting an electronic structure The electronic structure of an atom can be predicted from its atomic number. For example, the atomic number of sodium is 11. Sodium atoms have 11... 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
