stable and chemically nonreactive, or inert.
Atoms whose outer electron shells contain eight electrons tend to be stable and do not easily form ionic bonds in aqueous solutions. This is because they have reached the stable configuration known as the octet rule. In most cases, atoms that form ionic bonds have outer electron shells that are not fully filled with eight electrons.
The number of valence electrons in an atom determines if it is inert or reactive. Inert atoms have a full outer electron shell and are stable, while reactive atoms have incomplete outer electron shells and tend to react with other atoms to achieve a stable electron configuration.
Most atoms become less reactive after gaining a full outer electron shell, which typically happens after reaching a total number of eight valence electrons (octet rule). This configuration stabilizes the atom, reducing its tendency to react with other atoms.
Atoms tend to achieve stability by filling their outer shell with electrons, typically aiming for a full set of eight electrons, known as the octet rule.
The Octet rule is for eight(8) electrons in the outer most energy shell. NB Remember 'Octa' from Latin , means '8' ( eight).
The Outermost Electrons are the reactive particles of the atoms.

Atoms can be reactive if they have an incomplete outer electron shell. This can result in the atom either gaining, losing, or sharing electrons with other atoms to achieve a stable electron configuration. Some common reactive atoms include those from the halogen and alkali metal groups.

Most atoms require eight electrons in the outer shell to be stable. The exception is atoms that are only filling the s1 orbital, which becomes stable with only two electrons.
The Octet rule is for eight(8) electrons in the outer most energy shell. NB Remember 'Octa' from Latin , means '8' ( eight).
Alkali earth metals have 2 electrons in their outer energy level. This outer level is known as the valence shell, and having 2 electrons makes these metals highly reactive and likely to form ionic bonds to achieve a full outer shell of 8 electrons.
That isn't necessarily true. The Halogens (group 17) follow what you said, but the Alkali metals (group 1) don't. As you go down the column, the elements get more reactive for group 1; Lithium is the least reactive and Francium (speculated) is the most reactive. On the other hand, as you down the Halogens, they do get less reactive. Astatine (speculated) is the least reactive while Fluorine is the most reactive element of them all. Hope that clears up things!
Other atoms are reactive because they are constantly seeking to attain a stable electron configuration. Atoms will interact with other atoms in order to gain, lose, or share electrons to achieve a full outer shell of electrons, which is the most stable configuration. This reactivity is driven by the desire to achieve a lower energy state.
They already have eight valence electrons in their outer shell Which means the outer layer is full.
