Take a look in ~ the photo below. Each of those fancy balls is one electron. In an atom, the electrons spin roughly the center, additionally called the nucleus. The electrons like to be in different shells/orbitals. Shell number one deserve to only hold 2 electrons, shell two can hold 8, and for the an initial eighteen aspects shell three deserve to hold a preferably of eight electrons. As you learn about elements with an ext than eighteen electron you will uncover that covering three can hold more than eight. When one covering is full, the following electron the is added has to move to the following shell.So... For the aspect of NEON, you already know that the atomic number speak you the number of electrons. That way there room 10 electron in a neon atom. Looking in ~ the picture, you deserve to see there room two electrons in covering one and eight in covering two. Since shell two has actually eight electron it is now full.

NeonHey! Neon (Ne) is the second of the noble gases. Just like all noble gases, the is very non-reactive. So lot so, that it doesn"t type compounds v anything. Just like helium (He) and argon (Ar), neon floats about all through itself.It is non-reactive since it"s shells space full. Because neon has two atom shells, it requirements two electrons in the very first and eight to to fill the second. Neon has a complete of ten electrons which means two fill shells.
