It is the only noble gas not to have eight valence electrons. As the valence electron decides the block of the element if the last electron enters in the s-subshell then the element is of s-block. Valence electrons are the outer shell electrons in an atom. GET 20 OFF GRADE YEARLY SUBSCRIPTION Pricing.
Now I am going to show you how many valence electrons helium have in just 5 steps. Helium is one of the most significant member of the noble gas family that can be found on the upper right side of the periodic table. Have you ever played cards. From periodic table we see that the atomic number of helium is 2.
- The atomic number of helium is 2 so there are two electrons in the helium atom therefore its configuration will be 1s2. The reason is because the first electron shell the 1s orbital only requires two electrons to be complete. The atomic number of Helium is 2. We can also find the valency of helium with the help of the periodic table.

While playing cards we often deal with games that include getting cards from other players to fulfil the games objective like grouping four sevens four aces etc. A 2 B 4 C 6 D 8. How many electron shells does helium have An early model of the atom was developed in 1913 through the Danish scientist Niels Bohr 18851962. First find the atomic number of helium from periodic table.
The last and only level of heliums electronic configuration is 1 s 2 and therefore H e has 2 valence electrons. How Many Valence Electrons Does Helium HaveNumber of Valence Electrons in HeliumWhy does helium only have two valence electronsRead My Blogposthttps.
