The rule is that all of the orbitals (respectively - all of shells and blocks) of the element must be filled with their maximum number of electrons.Such phenomenon is observed in the noble gases (group VIII A) - their last blocks - s and p are filled with the total number of 8 electron (2 for s and 6 for p).
For instance - The Argon (Ar) has 18 electrons and its configuration is:
1s22s22p63s23p6

When is an element said to be chemically reactive?
An element is said to be chemically reactive when it combines with another element. These two elements will create a new compound.
What is the noble gas configuration of francium?
The noble gas configuration of francium is [Rn]7s^1, where [Rn] represents the electron configuration of radon, a noble gas element. Francium has one valence electron in the 7s orbital, making it highly reactive.
What is the electron configuration of a element of 16 electrons?
The electron configuration of sulfur is [Ne) 3s2.3p4.
If an element has a total of 86 electrons is it inert reactive or non reactive?
An element with 86 electrons is reactive because it is not a noble gas and does not have a full outer electron shell. Elements tend to react to achieve a stable electron configuration, such as by gaining or losing electrons to achieve a full outer shell.
Is bore reactive or not?
Boron is typically considered to be a reactive element, as it readily forms compounds with other elements due to its electron configuration. It can react with oxygen, halogens, and metals to form various boron compounds.
Which element is the most reactive non metal?
Fluorine is the most reactive non-metal element. It readily gains an electron to achieve a stable electron configuration, making it highly reactive.
