WebAn atom will gain electrons if it has four to seven electrons in its outermost orbit. In such cases, it is easier to accept electron rather than donating it. Therefore, we determine the valency by subtracting the numbers of electrons from 8. All noble gases have 8 electrons in its outermost orbit except helium. Helium has 2 electrons in its ... WebHelium is a chemical element with the symbol He and atomic number 2. Helium is the 2 element on the periodic table. It is located in group 18 and period 1 in the modern periodic table. ... Helium has 0 valence electrons. Helium has 2 electrons out of which 0 valence electrons are present in the 1s2 outer orbitals of atom. WebThe duet rule or duplet rule of the first shell applies to H, He and Li—the noble gas helium has two electrons in its outer shell, which is very stable. (Since there is no 1 p subshell, 1 s is followed immediately by 2 s, and thus shell 1 can only have at most 2 valence electrons). flintstones imdb
