Question

What is the predicted electron configuration of Helium

Answer 1

1s²

Explanation:

The predicted electron configuration of Helium 1s².

Helium is an element with atomic number of 2. it is located on the last group on the periodic table.

• Electron distribution into the energy levels or sublevels of atoms can be shown using electronic configurations.

Here, the two electrons in Helium fills the first energy level with s-sublevel first.

The maximum number of electrons in the sub-level is 2: this gives the 1s² configuration.
