Ответ:
The valence electrons are located in an atom's outermost energy level
Further explanationIn an atom, there are levels of energy in the shell and subshell
This energy level is expressed in the form of electron configurations.
Electrons fill the orbitals based on the Aufbau principle, namely the filling of electrons starts from the lowest energy level
Electron dotsUsually used in describing Lewis structures, placed around the element
Quantum electronsEach orbital in an atom consists of 4 quantum numbers : n, l, ml, ms
Each electron has a different quantum number and this conforms to Pauli's rule: no electrons have the same 4 quantum numbers
Valence electronsValence electrons are electrons used in a chemical bond , and in an atom's outermost energy level
Noble-gas electronsNoble gas has a stable electron configuration of 8 valence electrons which guides the formation of chemical bonds called the octet rule
