The 3p level
2 the s and p sublevels
Level 2
Sublevels
Outermost have more energy than innermost. As electrons move inward, they release energy.
There are four energy sublevels in the fourth energy levels: 4s, 4p, 4d, and 4f.
The 2s and 2p sublevels in the second principal energy level are completely occupied in the ground state of a sodium atom.
2 the s and p sublevels
Depends on what one means by "smaller". Since sublevels are "inside" or part of the principle energy level, then yes, they are smaller.
The outermost principle energy level for strontium is the 5th energy level.
Level 2
The second principle energy level is the energy level that comes after the first principle energy level. The second energy level is farther from the atomic nucleus and contains the 2s and 2p sublevels.
By the first principle energy level I assume you are referring to the lowest atomic orbital or ta principal quantum number of 1. This orbital holds 1 pair of 2 electrons.
An electron in the outermost energy level of an atom is called a valence electron.(We refer here to the outermost occupied levels of an atom. There are, of course, many other higher energy levels normally available that are not occupied.)These electrons determine the chemical reactivity of the atom.the valence electrons
Because it has it has eight electrons in the outermost occupied energy level.
There are 2 energy sublevels in the second principal.
There are two sublevels in the 2nd principal energy level. They are the 2s and 2p sublevels.
Each electron occupies the lowest energy orbital. Orbitals related to energy level are of equal energy.
