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.

What sublevel in group 2 elements are valence electrons?
s
Why aren't there any p-block elements in the first period of the periodic table?
Because in the first period, only the first energy level is being filled with electrons, which can take only a maximum of 2 electrons in the s sublevel. The electron configuration of hydrogen is 1s1 and helium is 1s2. There is no p sublevel in the first energy level.
How many electrons are in the first period?
for all elements, excluding hydrogen, there are 2 electrons in the first energy level. Hydrogen is the exception of this because it only has a single electron, thus it only has 1 in its first and only energy level.
Number of electrons on an s sublevel in the outermost electron shell of the group IA?
one electron
What is the number of electrons for a Zr?
im pretty sure it is 2. i was hoping to find the answer to this online, but it turns out I'll be answering it This is the electron configuration for Zr: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d2 and there are 2 electrons in the outermost energy level of 5. BTW, if you do not know about electron configs, they are based on the periodic table an are in the format of nle where n is the energy level (1,2,3,4...); l is the sublevel (s,p,d,f in that order) and e is the number of electrons. S sublevel can fit 2, P 8, D 18, and F 32. ^^^ Number of electrons per sublevel is calculated using the formula of twice the sublevel squared. Good luck!
What sublevel in group 2 elements are valence electrons?
s
Why can a p sublevel hold 6 electrons while the s sublevel can hold no more than 2 electrons?
because sublevel p has 3 orbital and each orbital can hold up to 2 electrons meanwhile sublevel s only has 1 orbital and each can hold 2 electrons therefore sublevel p can hold more
How many electrons are found in each sublevel?
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.
How many electrons can the S sublevel hold?
there are two electons in the s sublevel. It is the number of electrons that fit in the first orbital around an atom.
Which element has its outermost electrons in an S sublevel?
The elements belonging to Group IA and IIA.
How many electrons are in the g sublevel?
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.)
What are the relationships between group configuration and group number for elements in the s p and d-blocks?
There are one or two electrons in the ns sublevel for s-block elements, the sum of electrons in ns and (n-1)d levels equals the group number in d-block elements, and the number of electrons in the np sublevel equals the group number minus twelve in p-block elements. You can find this info in table 2 on page 147 of the Modern Chemistry textbook.
What is the maximum number of electrons that can go into sublevel 2s?
The maximum number of electrons in any s sublevel is 2, irrespective of what the principal quantum number, i.e., the number before the s in an electron configuration, may be.
What is the maximum number of electrons that the f sublevel can hold?
f has 14 electrons in 7 sublevel orbitals,d has 10 electrons in 5 sublevel orbitals,p has 6 electrons in 3 sublevel orbitals,s has 2 electrons in 1 sublevel orbital.
How many electrons are held in s sublevel?
s-sublevels holds only two electrons in maximum.
Why aren't there any p-block elements in the first period of the periodic table?
Because in the first period, only the first energy level is being filled with electrons, which can take only a maximum of 2 electrons in the s sublevel. The electron configuration of hydrogen is 1s1 and helium is 1s2. There is no p sublevel in the first energy level.
What element has 2 electrons in the 1s sublevel and 4 electrons in the 2s level?
An element cannot have 4 electrons in the 2 s level. The s subshell can hold only TWO electrons. Carbon has 4 electrons in the 2p level, however, if that's what you meant.
