2 electrons in the only shell helium has.
only 2 electrons.
There are 8 electrons in the outer level of all the noble gases except helium. This full outer level gives them stability and makes them less reactive. Helium, as a noble gas, has only 2 electrons in its outer level.
it is Helium.
Hydrogen and Helium
They have 8 valence electrons (except for helium which has 2 valence electrons).
Outermost shell
Sulphur has 6 electrons in its outermost shell.
the number of electrons found in the third shell of an helium atom are nill because its atomic number is 2
The electrons found in the outermost shell (or energy level) are known as the valence electrons.
A duplet state is when an element has two electrons in it's outermost shell For example-Helium
Their outermost electrons are in the same shell. For example, Helium and Hydrogen have 1 and 2 electrons respectively, and these electrons exist within the first electron shell. Lithium has 3 electrons and the third of these electrons is in the second electron shell, and so, it is a member of the 2nd period of the periodic table.
Well, darling, that element you're looking for is helium. It sits pretty on the periodic table with its full outermost energy level of 2 electrons, living its best life. So, there you have it, helium is the sassy star of the show with its energy level on lock.
