What is the extranuclear electronic configuration of elements 33 to 40

Summary. Extranuclear electron configuration: 1 20 element (remember the name of the element and the schematic diagram of the atomic structure).

Layout rules. Each layer has a maximum of 2n2 electrons (n represents the number of layers), and the outermost shell does not exceed 8 electrons (the outermost shell is the first layer, no more than 2), which first fills the inner shell and then discharges the outer shell.

Note: The chemical properties of an element depend on the number of electrons in the outermost shell.

The outermost electron number of the metallic element atom is < 4, volatile electrons, and chemically active.

The outermost electron number of the non-metallic element atom is 4, and the electrons are easily obtained, and the chemical properties are lively.

Noble gas element The outermost shell of the atom has 8 electrons (HE has 2), which is stable in structure and stable in nature.

Layout rules:Construction principle: the lower the energy of the whole system, the better. In general, the newly filled electrons are filled in the empty orbital with the lowest energy.

Hinder's rule: Electrons occupy as many orbits as possible and spin in the same direction.

Pauli's incompatibility principle: In the same system, no four quantum numbers with two electrons are exactly the same.

Energy level staggering: A phenomenon in which the energy of some orbitals with a large number of electron layers is lower than the energy of some orbitals with a smaller number of electron layers.
