the 2s orbital is at a higher energy level
The 2s orbital is larger than the 1s orbital and is higher in energy.
The 2s orbital and 3s orbital both have the same spherical shape and can hold a maximum of two electrons of opposite spin. They only differ because the 3s orbital is further out from the nucleus than the 2s orbital, thus the 3s orbital has a higher energy value.
An electron in a 2s orbital is on average closer to the nucleus.
A total number of 8 electrons. Two in the 2s orbital and six in the 2p 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.

An electron is lost from the 2s orbital
The number preceding the name of a sublevel ("s") indicates in which electron shell it belongs. Thusly, 2s is the second shell and 3s is the third.
You can tell the difference between 2s sub-shell and 2p sub-shell by checking their energy levels whereby a 2p orbital has a higher energy level compared to a 2s orbital.
