Where there are 8 electrons in the outer shell so a full shell. Elements are reactive when they need to lose or gain an electron. The noble gases are unreactive as they have a full outer shell.

Why are alkali metals more reactive than other metals?
Alkali metals are more reactive as they are in group 1 and therefore has only one valence electron. With only one valence electron, its easy for them to achieve inert configuration/ noble gas configuration, which makes them so reactive.
Which are more chemically reactive halogens or noble gases?
Noble gases have completely filled orbitals and hence are generally chemically inert. Halogens are highly reactive as they need one more electron to complete octet.
Why the metal is very reactive?
Metals , generally, have electronic configuration: with outermost electron having 1,2 or 3. Since, they can easily attain noble gas configuration to attain stability; they readily loose electron.
Is sodium or argon more reactive and why?
Argon has completely filled valence orbitals and hence is unreactive. Sodium has one valence electron. If sodium loses this electron it will attain the stable electron configuration of the nearest noble gas (argon) and hence is reactive.
What is the most chemically reactive ion?
The most chemically reactive ion is the hydrogen ion.
Why lithium highly reactive?
if lithium loses one electron it attains the stable noble gas electron configuration of helium. hence it is highly reactive.

Why is a noble gas inert?
Noble gases have a stable electron configuration. So they are less reactive.
Are atoms with eight electrons in the outer shell not reactive at all?
stable and chemically nonreactive, or inert.
Is nicotine reactive?
Yes, nicotine is chemically reactive.
What makes the elements in the halogen group reactive?
they need one more electron to attain noble gas configuration and hence are highly reactive.

The most chemically reactive ion is the hydrogen ion.
Which is more reactive chlorine or argon?
Argon is chemically inert due to the presence of filled orbitals. Chlorine is highly reactive as it requires one more electron to gain octet.
What is the electron configuration for a element that's not chemically reactive?
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
