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.
The fluorine ion (F-) is known to be one of the most chemically reactive ions due to its high electronegativity and ability to readily accept electrons to achieve a stable electron configuration. It forms strong bonds with other elements, leading to highly reactive compounds.
Halogens are more chemically reactive compared to noble gases. Halogens have a high tendency to gain an electron to achieve a stable electron configuration, while noble gases already have a full outer electron shell and are therefore less likely to react with other elements.
Noble gases are chemically inert, meaning they are generally non-reactive with other elements. This is due to their stable electron configuration, with a full outer shell of electrons. This makes noble gases very useful in applications where a non-reactive atmosphere is required.
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
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.
No, sodium (Na) is more chemically reactive than lithium (Li) because sodium has an outer electron configuration that makes it more likely to lose an electron and form compounds.
Fluorine, oxygen, chlorine.

The halogens, which is group 17, are the most reactive non-metals. Oxygen is pretty reactive too, even though it's not a halogen.
Noble gases are chemically inert, meaning they are generally non-reactive with other elements. This is due to their stable electron configuration, with a full outer shell of electrons. This makes noble gases very useful in applications where a non-reactive atmosphere is required.
Sodium is not considered chemically stable because it is highly reactive. It readily forms compounds with other elements, particularly halogens like chlorine, to achieve a more stable electron configuration. Sodium is stored under oil or in a dry environment to prevent its reactivity with air and moisture.
if lithium loses one electron it attains the stable noble gas electron configuration of helium. hence it is highly reactive.

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.
The halogen group elements are reactive because they have seven valence electrons, making them one electron short of a full outer shell. They are highly reactive and tend to gain an electron through reactions with other elements to achieve a stable electron configuration.
The column next to the noble gases in the periodic table is the halogens group. Halogens are highly reactive because they only need one more electron to complete their outer electron shell and achieve a stable electron configuration. This makes them eager to chemically react with other elements to gain that electron and become stable.
