The elements with atomic numbers 2, 10, 18, 36, 54 and 86 are all :
Open in App
Solution
The correct option is C noble gases
According to Bohr, as per the energy level, the filling of electrons in each shell will be 2, 8, 8, 18, 32. The atomic number given are 2, 10, 18, 36, 54, 86 which shows that these elements have completely filled orbitals and are noble gases or zero group members.
