One option is a helium atom.
Another is a Lithium cation.
Or a beryllium cation.
Or boron for that matter.
Cause Li would be 1s2 2s1, Be would be 1s2 2s2 and Boron would be 1s2 2s2 2p1 so if they were to lose their valence electrons to become ions (cations) then they would have a 1s2 orbital.

1s and 2s orbitals differ in that 2s orbitals lie farther away from the nucleus in the next principle energy level. Other than that, they occupy the same shape of orbital, spherical, as indicated by the s.
In lithium, the orbital of highest relative energy is the 2s orbital. This is due to the fact that, in the electron configuration of lithium (1s^2 2s^1), the 2s orbital is farther from the nucleus compared to the 1s orbital, resulting in higher energy.
The complete electron configuration of lithium is 1s^2 2s^1. This means that lithium has 3 electrons, with 2 electrons in the 1s orbital and 1 electron in the 2s orbital.
The electron configuration for lithium is 1s^2 2s^1. This means that lithium has 3 electrons, with two in the 1s orbital and one in the 2s orbital.
the 1s orbital is closer to the nucleus and has a lower energy level compared to the 2s orbital. Additionally, the 2s orbital has a slightly higher energy, larger size, and can hold more electrons than the 1s orbital.
The 2s orbital is larger than the 1s orbital and is higher in energy.
Electronic configuration of boron: [He]2s2.2p1.

1s is a real orbital, specifically the lowest energy orbital in an atom. It is a spherical orbital that is closest to the nucleus and can hold a maximum of 2 electrons.
The complete electron configuration of lithium is 1s^2 2s^1. This means that lithium has 3 electrons, with 2 electrons in the 1s orbital and 1 electron in the 2s orbital.

It has 1 electron revolving around 1 proton in the 1s orbital.It has 1 proton and 1 electron revolving in the 1s orbital
The first orbital of hydrogen, which is the 1s orbital, can hold a maximum of 2 electrons.
the 1s orbital is closer to the nucleus and has a lower energy level compared to the 2s orbital. Additionally, the 2s orbital has a slightly higher energy, larger size, and can hold more electrons than the 1s orbital.
One only - 1s.
An atom can have only one 1s orbital. This orbital can hold up to a maximum of 2 electrons.
