no. of electrons to fill an energy level = 2n2.
= 2x32 = 18
6
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.
valence electrons are the electrons in the outermost energy level
Valence electrons are the electrons in the outermost energy level.
Electrons in the outermost principal energy level are called valence electrons.
2
Completely filled octet.
More energy have the electrons in the second level of energy.
it is called complete or completely stable
Completely filled octet.
6
8 electrons
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Helium has two electrons which completely fills the first principal quantum level.
If the atom is chemically stable it doesnt need to bond, it is chemically stable when the outermost level is completely full of electrons
