Question

Наведіть приклад двох катіонів і двох аніонів що мають таку саму електронну оболонку як атом Неону

Answer 1

Атоми із завершеними енергетичними рівнями, або на зовнішньому рівні яких міститься вісім електронів (виняток Гелій - два)

Answer 2

Atoms with Electron Configuration Similar to Neon

The electron configuration of neon is 1s^2 2s^2 2p^6. This means it has 10 electrons in total, with 2 in the first energy level and 8 in the second. Let's find cations and anions with a similar electron configuration.

Cations with Similar Electron Configuration

One example of a cation with a similar electron configuration to neon is the aluminum ion (Al^3+). Aluminum has an electron configuration of 1s^2 2s^2 2p^6 3s^2 3p^1 in its neutral state. When it forms a cation by losing 3 electrons, its electron configuration becomes 1s^2 2s^2 2p^6, which is the same as that of neon.

Anions with Similar Electron Configuration

One example of an anion with a similar electron configuration to neon is the fluorine ion (F^-). Fluorine has an electron configuration of 1s^2 2s^2 2p^5 in its neutral state. When it forms an anion by gaining 1 electron, its electron configuration becomes 1s^2 2s^2 2p^6, which is the same as that of neon.

These examples demonstrate how cations and anions can achieve a similar electron configuration to neon by either losing or gaining electrons to attain a stable noble gas configuration.
