Question

How many valence electrons do the noble gases possess in the second period and below in the periodic table? How many valence electrons do the noble gases possess in the second period and below in the periodic table? 1 2 7 6 8

Answer 1

Noble gas which belongs to second period is Neon ( Ne ) which has atomic number = 10

its electronic configuration = 2 , 8

so it has 8 valence electrons .

Only Helium ( He ) has 2 valence electrons while all the other noble gases like Neon ; Argon , Krypton, Xenon and Radon has 8 electrons in their valence shell.
