What is 1s 2s 2p in chemistry?
The superscript is the number of electrons in the level. The number in front of the energy level indicates relative energy. For example, 1s is lower energy than 2s, which in turn is lower energy than 2p. The number in front of the energy level also indicates its distance from the nucleus.

What makes up the s block on the periodic table?
The “s block” on the periodic table are groups 1 and 2; they end in s1 and s2. The “p block” on the periodic table are groups 13-18 and end in p1, etc. The “d block” on the periodic table are groups 3-12 make up the d block and the elements’ electron configurations end in d.
Why are the subshells of the periodic table not the same?
1s < 2s = 2p <3s = 3p = 3d < 4s = 4p = 4d = 4f < However, for a multielectron atom or ion (an atom or ion containing a nucleus and more than one electron), the energies of the subshells are no longer the same because of the various electron-electron interactions and generally follow the order
What do the grayed out numbers on the periodic table mean?
Grayed out electron numbers indicate subshells that are filled to their maximum. The bracketed noble gas symbols on the left represent the inner configurations that are the same in each period. Written out these are: He, 2, helium : 1s 2
What are the numbers on the periodic table?
1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f ≈ 5d < 6p < 7s < 5f ≈ 6d < 7p <
