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.

How does 2s orbital differ from a 1s 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.
How many orbitals are im the first energy level?
One only - 1s.
Why electrons pairing start with only 2p orbital in P subshell?
Electrons start pairing in the 1s orbital. A 1s orbital can take two electrons, represented by 1s2.
The major difference between a 1s orbital and a 2s orbital is that?
the 2s orbital is at a higher energy level
Which orbital is the first to be filled in any atom?
the first orbital to be filled is 1s because in this orbital the negatively charged electron is closer to the positively charged nucleus than in any other orbital Quoted directly from my Chenistry Text Book ( World of Chemisty Zumdahl/Zumdahl/DeCoste , p377 McDougal Littell 2007)
How a 1s orbital different from a 2s orbital in terms of size?
The 2s orbital is larger than the 1s orbital and is higher in energy.
How does 2s orbital differ from a 1s 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.
What is hydrogen atomic structure?
It has 1 electron revolving around 1 proton in the 1s orbital.It has 1 proton and 1 electron revolving in the 1s orbital
How many orbitals are im the first energy level?
One only - 1s.
Why electrons pairing start with only 2p orbital in P subshell?
Electrons start pairing in the 1s orbital. A 1s orbital can take two electrons, represented by 1s2.
Which orbital gives an electron the greatest probability of being found close to nucleus?
The 1s orbital.
What is the atomic structure of hydrogen?
Hydrogen is an element. Its atomic number is one. It has one proton in the nucleus, and one electron in the first orbital. It has no neutrons.
What do elements in periods have in common?
They all have a filled 1s orbital
The major difference between a 1s orbital and a 2s orbital is that?
the 2s orbital is at a higher energy level
What is the electron shell configuration or Nitrogen?
The electron configuration of nitrogen is 1s^2 2s^2 2p^3. Nitrogen has a total of seven electrons, with two in the 1s orbital, two in the 2s orbital, and three in the 2p orbital.
In which orbital does an electron in a phosphorus atom experience the greatest shielding?
1s
What is the valence shell for nitrogen?
Nitrogen (N) has atomic number 7. It has full 1s and 2s orbitals. The 2px orbital has 1 electron, the 2py orbital has 1 electron and the 2pz orbital has 1 electron. So the valence shell is: 2s2 - 2p3. It contains 5 electrons.
