i think it is (1, 0, 1, -½), but i am not sure....
When helium loses an electron, it becomes a positively charged helium ion (He+).
Hydrogen and helium have different valence electron configurations. Hydrogen has one valence electron, and helium has two valence electrons. However, hydrogen does typically form covalent bonds in which it shares an electron, and thereby gains an effective electron configuration of two, like helium. Hydrogen also can form the H+ ion which has no electrons.
hydrogen (H) and helium (He)
The ground state electron configuration of hydrogen is 1s^1, meaning it has one electron in the 1s orbital. Helium in its ground state has an electron configuration of 1s^2, indicating it has two electrons in the 1s orbital. So, the main difference is that hydrogen has one electron in its outer shell while helium has two electrons in its outer shell.
Helium has 2 valence electrons and hydrogen has 1 electron. So, they are placed in different groups.

Helium has two electrons which completely fills the first principal quantum level.
A possible quantum number set for an electron in a ground-state helium atom could be n1, l0, m0, s1/2.
The emission wavelengths for helium and hydrogen differ because they have different electron configurations. Helium emits light at specific wavelengths corresponding to its unique electron transitions, while hydrogen emits light at different wavelengths due to its own electron transitions.
hydrogen (H) and helium (He)
The atomic number of helium is one more than that of hydrogen. In both the elements, the electrons are filled in the 1s orbitals. Hydrogen has one electron, helium has two.
The ground state electron configuration of hydrogen is 1s^1, meaning it has one electron in the 1s orbital. Helium in its ground state has an electron configuration of 1s^2, indicating it has two electrons in the 1s orbital.

helium is after haydrogen it means hygrogen is lighter than helium. now the question arises that "Q.1"why we use helium instead of hydrogen coz hydrogen is lighter than helium. Ans.1:hydrogen has 1 electron in its 1st shell and helium has it's complete shell with two electron. When we fill hydrogen in the baloon they form ionic bond... so it is used double...
Hydrogen and Helium
Helium is already stable. Hydrogen should gain or lose one electron to be stable.
Helium has 2 valence electrons and hydrogen has 1 electron. So, they are placed in different groups.
