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.)

The largest number of electrons found in the first energy level?
Two (in the case of helium).
How many electrons are in level two of helium?
There are no electrons present in a helium atom in its second energy level.
How many electrons are in the third energy level of helium?
Helium has only one energy level with two electrons. It does not have electrons in other energy levels in its ground state.
What element is a noble gas in the first energy level?
There are no noble gases in the first energy level. Noble gases are found in the last (highest) energy level of an atom. The first energy level can only hold a maximum of 2 electrons, while the noble gases have completely filled outermost energy levels.
How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs 2 valence electrons to have a filled outermost energy level.
How many electron does helium have in its first energy level?
1
The largest number of electrons found in the first energy level?
Two (in the case of helium).
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
How many electrons are in level two of helium?
There are no electrons present in a helium atom in its second energy level.
How many electrons are in the third energy level of helium?
Helium has only one energy level with two electrons. It does not have electrons in other energy levels in its ground state.
What element has one main energy level?
Helium has two electrons which completely fills the first principal quantum level.
What element is a noble gas in the first energy level?
There are no noble gases in the first energy level. Noble gases are found in the last (highest) energy level of an atom. The first energy level can only hold a maximum of 2 electrons, while the noble gases have completely filled outermost energy levels.
How many levels does helium have?
Helium has only one energy level with two electrons
What element that is considered unreactive because it has a filled outer energy level is?
noble gases helium to be exact
How many levels of electrons does helium have?
One energy level
How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs 2 valence electrons to have a filled outermost energy level.
What is heliums enery level?
helium has only one energy level (with 2 electrons in it).
