The first energy level in the quantum (current) theory of the atom is the 1s electron orbital, which can hold two electrons.
The following energy levels go like this:
1s22s22p63s23p64s24p63d105s25p64d106s2...
And so on. (The first number being the energy level, the letter being the shape of the electron orbital, and the superscript being the number of electrons the orbital can hold.)
What else can I help you with?
How many electrons are in the third energy level of helium?
Oh, dude, helium only has two electrons total, so there can't be any in the third energy level. It's like trying to fit a square peg in a round hole - just not gonna happen. So, zero electrons in the third energy level of helium.
The largest number of electrons found in the first energy level?
Two (in the case of helium).
What is the electron shell diagram for helium?
Helium has one energy shell with only 2 electrons in it.
How many number of electrons of helium in outer ring?
Helium has only two electrons with one ring (or energy level). Both the electrons are in the one and only energy level / shell / ring.
Helium atoms only need how many valence electrons to have a filled outermost energy level?
Helium atoms only need 2 valence electrons to have a filled outermost energy level because helium is in the first period of the periodic table and its outermost energy level can only hold a maximum of 2 electrons.
How many electron does helium have in its first energy level?
Helium has 2 electrons in its first energy level.
Does an atom of helium have eight electrons in its outer energy level?
the largest number of electrons an atom of helium can have is 2, because it is in the first period, which means it can only have one energy level, which has a maximum capacity of two electrons
If the first energy level is complete with two electrons then what has two elements?
If the first energy level is complete with two electrons, then the elements hydrogen and helium have two elements in their electron configuration. Hydrogen has one electron in its first energy level, while helium has two electrons filling its first energy level.
The largest number of electrons found in the first energy level?
Two (in the case of helium).

What element has atoms with only one completely filled principal energy level?
undiscovered...yet, but there are a few...go forward 50 years and see
Helium atoms only need how many valence electrons to have a filled outermost energy level?
Helium atoms only need 2 valence electrons to have a filled outermost energy level because helium is in the first period of the periodic table and its outermost energy level can only hold a maximum of 2 electrons.
What element has one main energy level?
Helium has two electrons which completely fills the first principal quantum level.
What is the highest occupied energy level in He?
It is 2p. Because the electron configuration for oxygen is 1s2 2s2 2p4, therefore 2p being the greatest or highest energy level
How many electrons are in level two of helium?
There are no electrons present in a helium atom in its second energy level.
