Question

Электронная формула иона Al+

Answer 1

Al⁺ Электронная конфигурация :

1s²2s²2p⁶3s²

Answer 2

The electron configuration of an ion represents the arrangement of electrons in its energy levels and orbitals. For the ion Al+, we need to determine the electron configuration for the aluminum cation (Al+).

Aluminum (Al) has the atomic number 13, which means it has 13 electrons in its neutral state. When aluminum loses one electron to form the cation (Al+), it becomes positively charged.

The electron configuration of the neutral aluminum atom (Al) is:

1s^2 2s^2 2p^6 3s^2 3p^1

To form the Al+ ion, one electron is removed from the 3p orbital, since it has the highest energy level:

1s^2 2s^2 2p^6 3s^2

So, the electron configuration of the Al+ ion is:

1s^2 2s^2 2p^6 3s^2
