Question

Являются ли электронными аналогами элементы с порядковыми номерами 22 и 40 ответ поясните

Answer 1

У 22 и 40 элемента на последней энергетической оболочке по 2 атома электрона.

Answer 2

Are elements with atomic numbers 22 and 40 electronic analogs?

No, elements with atomic numbers 22 and 40 are not electronic analogs.

The electronic configuration of an element is determined by the distribution of its electrons in different energy levels and sublevels. Elements with the same electronic configuration are considered electronic analogs.

The element with atomic number 22 is titanium, and its electronic configuration is [Ar] 3d2 4s2. On the other hand, the element with atomic number 40 is zirconium, and its electronic configuration is [Kr] 4d2 5s2.

These electronic configurations clearly indicate that titanium and zirconium have different electronic structures, and therefore, they are not electronic analogs.

This conclusion is based on the electronic configurations of titanium and zirconium, as provided by the periodic table
