Question

electron configuration is the distribution of electrons in atomic orbitals of an atom. the electrons in the outermost shell (or shells) determine the chemical properties of the atom. for example, the electron configuration of chlorine is 1s²2s²2p⁶3s²3p⁵. a chlorine atom has seven electrons in its outermost shell. electron configurations of elements change systematically across a row in the periodic table. the elements of elements in the same group of the table have related outer shell electron configurations. for example, fluorine, chlorine, bromine, iodine, astatine, and tennessine have related outer shell electron configurations.

Explanation:

Puedes preguntar sobre cómo la configuración electrónica de los elementos en una misma columna de la tabla periódica les permite tener propiedades químicas similares.

Answer:

¿Por qué los elementos de la misma columna en la tabla periódica tienen configuraciones electrónicas de la capa exterior relacionadas y cómo afecta esto a sus propiedades químicas?
