Question

Какая из электронных конфигураций наиболее устойчива?а) 1s²2s²2p²б) 1s²2s²2p⁶3s²в) 1s²2s²2p⁶3s²3p⁶4s²3d⁵г) 1s²2s²2p⁶

Answer 1

Электронные конфигурации наиболее устойчивы, когда на внешней оболочке имеется 8 электронов.
Ответ: а) 1s²2s²2p²

Answer 2

Most Stable Electronic Configuration

The most stable electronic configuration is the one that follows the octet rule, which states that atoms tend to combine in such a way that each atom has eight electrons in its valence shell. Let's analyze the given electronic configurations to determine the most stable one.

a) 1s²2s²2p² b) 1s²2s²2p⁶3s² c) 1s²2s²2p⁶3s²3p⁶4s²3d⁵ d) 1s²2s²2p⁶

The electronic configuration that is most stable is option c) 1s²2s²2p⁶3s²3p⁶4s²3d⁵. This configuration satisfies the octet rule for the elements involved, making it the most stable configuration .

Therefore, among the given options, option c) is the most stable electronic configuration.
