The p-block elements of period 4 have their valence shell composed of 4s and 4p subshells of the fourth ( n = 4) shell and obey the octet rule . For quantum chemistry namely this period sees transition from the simplified electron shell paradigm to research of many differently-shaped subshells.

Tabela periódica. Versão mais recente da Tabela Periódica, terminando no Oganessônio. A tabela periódica é uma disposição sistemática dos elementos químicos ordenados por seus números atômicos, configuração eletrônica, e recorrência das propriedades periódicas.
2 de mai. de 2024 · Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties.
Elements Wiki. Period 4 element. Period 4 comprises the elements from potassium (Z = 19) through krypton (Z = 36). In their ground states, all Period 4 atoms have an argon-like core surrounded by 4s and 4p electrons. In addition, 3d electron states are also possible for Period 4 elements.
