Take a look at the picture below. Each of those colored balls is an electron. In an atom, the electrons spin roughly the center, additionally called the nucleus. The electrons like to be in different shells/orbitals. Covering number one have the right to only host 2 electrons, covering two can hold 8, and for the an initial eighteen facets shell three have the right to hold a maximum of eight electrons. As you learn around elements with an ext than eighteen electron you will find that covering three deserve to hold more than eight. When one covering is full, the next electron that is included has to relocate to the next shell.So... Because that the element of HELIUM, you currently know the the atomic number tells you the variety of electrons. That means there space 2 electron in a helium atom. Looking in ~ the picture, you deserve to see there are two electron in shell one. That way the an initial shell is full.

HeliumHelium (He) is the an initial of the Noble Gases. The is very non-reactive. So much so, that it doesn"t form compounds v anything. Just like neon (Ne) and also argon (Ar), helium just floats around all through itself.It is non-reactive due to the fact that it"s shell is full. Helium only has one atomic shell, which filling up when it has two electrons.
