Question

Электронная формула (1s2 2s2 2p6....) ?

Answer 1

Это электронная формула элемента #10 Ne (Неон)

Answer 2

The electronic configuration you provided seems to be incomplete. However, I can help you complete it based on the periodic table.

The electronic configuration you started is often written for elements using the notation called the "orbital notation." It describes how electrons are distributed in different atomic orbitals. Let's continue the electronic configuration:

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6...

We continue this pattern following the Aufbau principle, which states that electrons fill the lowest energy levels first before moving to higher energy levels. The electronic configuration above continues indefinitely, and the pattern repeats as we go further into the periodic table.

Please note that this electronic configuration belongs to the noble gas element Radon (Rn) with atomic number 86. Since my knowledge cutoff is in September 2021, any new elements or updates beyond that date would not be reflected in this response.
