If you're talking about any s sublevel at all, then any element except hydrogen would fit that. If you're talking specifically about elements that have the s orbital as their valence (outermost) orbital, and also have that valence s orbital filled with 2 electrons, then helium and anything in the second column of the Periodic Table will all fit that description. (He, Be, Mg, Ca, Sr, Ba, Ra)
s
The valence electrons in group 2 elements are found in the s sublevel. These elements are known as alkaline earth metals and have 2 valence electrons, which occupy the s sublevel of their outermost electron shell.
The s sublevel in the third main energy level is indicated by 3s.
The hydrogen (H) sublevel, which corresponds to the 1s orbital, can hold a maximum of 2 electrons. Each sublevel can accommodate a specific number of electrons based on its type: s sublevels can hold 2, p sublevels can hold 6, d sublevels can hold 10, and f sublevels can hold 14 electrons. Therefore, for hydrogen, the single 1s sublevel has 2 electrons.
SPDF levels refer to the four sublevels in an electron shell: s, p, d, and f. These sublevels represent the different types of orbitals that electrons can occupy within an energy level. The s sublevel can hold up to 2 electrons, the p sublevel can hold up to 6 electrons, the d sublevel can hold up to 10 electrons, and the f sublevel can hold up to 14 electrons.
s
The element with its outermost electrons in an S sublevel is found in Group 1 and Group 2 of the periodic table. These elements have their outermost electrons in the S sublevel before transitioning to the D sublevel in subsequent groups.
The valence electrons in group 2 elements are found in the s sublevel. These elements are known as alkaline earth metals and have 2 valence electrons, which occupy the s sublevel of their outermost electron shell.
there are two electons in the s sublevel. It is the number of electrons that fit in the first orbital around an atom.
s-sublevels holds only two electrons in maximum.
Multiply the orbitals in that sublevel by 2. The s sublevel has one orbital and can contain 2 electrons. The p sublevel has three orbitals and can contain 6 electrons. The d sublevel has five orbitals and can contain 10 electrons. The f sublevel has seven orbitals and can contain 14 electrons.
The maximum number of electrons that can enter each type of sublevel in an atom are as follows: s sublevel: 2 electrons p sublevel: 6 electrons d sublevel: 10 electrons f sublevel: 14 electrons
The p sublevel consists of three orbitals, each of which can hold up to 2 electrons. This totals to a maximum of 6 electrons in the p sublevel. In contrast, the s sublevel consists of only one orbital, which can hold a maximum of 2 electrons due to the rules of electron configuration in an atom.
There are two sublevels in the second principal energy level: the s sublevel and the p sublevel. The s sublevel can hold a maximum of 2 electrons, while the p sublevel can hold a maximum of 6 electrons.
There are 9 orbitals in a g sublevel. (there is 1 in an s sublevel, 3 in a p sublevel, 5 in a d sublevel, 7 in an f sublevel, 9 in a g sublevel, 11 in an h sublevel, etc.)
2
The sixth energy level can hold up to 72 electrons, with each sublevel accommodating a specific number of electrons: s sublevel = 2 electrons, p sublevel = 6 electrons, d sublevel = 10 electrons, and f sublevel = 14 electrons.
