What is the electron configuration for helium (he)? 1s1 1s2 1s22s1 1s22s2

Answer : The electronic configuration for Helium is .

Explanation :

The group number of (He) = 18

The period number of (He) = 1

The atomic number of (He) = 2

Electronic configuration : It is defined as the distribution of electrons of an atom in an atomic orbitals.

Helium has 2 electrons around their nucleus.

So, the electronic configuration for Helium is .
