For a 2s subshell to be present, the 1s subshell must first be full, which means no more electrons can be moved into the 1s subshell.
You can tell the difference between 1s subshell and 3s subshell using quantum numbers and electron configuration.
it is just a quantum property, its further away from the nucleus
Electrons start pairing in the 1s orbital. A 1s orbital can take two electrons, represented by 1s2.
The electron configuration of neon is [He]2s2.2p6.

Na(1s^2 2s^2 2p66 3s^1) + F(1s^2 2s^2 2s^5) ----> NA+(1s^2 2s^2 2p^6) + F-(1s^2 2s^2 2p^6) Don't you love E20-20?
The electron configuration of neon is [He]2s2.2p6.
It has 1 electron revolving around 1 proton in the 1s orbital.It has 1 proton and 1 electron revolving in the 1s orbital
1s
The K shell's 1s orbital is te first energy level of an electron.
Hydrogen has a shell of just 1 electron. 1s
The 1S orbital will hold the innermost pair of electrons.
The single electron in a neutral hydrogen atom resides in the 1s orbital.
