Neon's valence shell contains eight electrons. Neon is a noble gas, and its outermost energy level is completely filled, making it stable and unreactive.
The outer shell is called the valence shell
The outer shell of an atom is called the valence shell. It contains the valence electrons, which are involved in forming chemical bonds with other atoms.
The outermost shell of electrons is called the "valence shell." It determines the chemical properties and reactivity of an atom.
The valence shell of boron has three electrons. Boron is in Group 13 of the periodic table, so it has three valence electrons in its outermost shell.
Nitrogen has 5 valence electrons. Its atomic number is 7 therefore it has a total of 7 electrons. If you put this in a Bohr-Rutherford Diagram, there would be 2 electrons in the first shell (Helium structure) and 5 electrons in the outer shell. The number of electrons in an element's outermost shell is its number of valence electrons.
