The electron configuration for helium (he) is shown below. 1s2 which diagram shows the correct distribution of electrons in the electron shells of a helium atom? mc024-1.jpg mc024-2.jpg mc024-3.jpg mc024-4.jpg mark this and return

As you can see in the picture presented below, Helium (He) is a noble gas with a stable 1s2 electron configuration.
This means that an atom of Helium has two electrons that are orbiting the atom's core in the first, S orbit. The two electrons are in the same orbit, but they orbit in opposite directions, they have an opposite spin.

Idon't know hope someone you

Green is technically every other color but green but the other wavelengths of the other colors get absorbed by the object and the wavelength of the color green gets reflected
