Atoms whose outer shell is filled have eight valence electrons and belong to Group XVIII. This group is known as the noble gases.
A completley filled out electron level makes the atom stable
No. The inner shells are filled first.
Yes. Argon has its outer electron shell full so doesn't easily react with other atoms.
Atoms want to be stable because stability leads to a lower energy state, which is more favorable. When atoms are stable, their outer electron shells are filled or partially filled, which results in a more balanced state. Atoms achieve stability by gaining, losing, or sharing electrons to reach a more stable electron configuration.
These are the valence electrons.
This answer is True!
No, atoms are most stable when their outermost electron shells are completely filled. This is because a full outer shell results in a lower energy state, making the atom more stable. Partially filled shells can lead to greater reactivity as atoms seek to fill or empty their outermost shell.
yes
true
When a compound is formed from two or more atoms of different elements, the chemical bonds that form cause the atoms in the compound to have filled valence shells.
Chlorine becomes a negative ion by gaining one electron to achieve a full outer electron shell, following the octet rule which states that atoms are most stable when their outer electron shell is filled with 8 electrons.
A completley filled out electron level makes the atom stable
Because it's in a stable state. Atoms with an electron 'missing' from their outer shell will always try to 'grab' one back to stabilize themselves. This is often done by combining with other atoms and 'sharing' an electron in order to reach stability.
No. The inner shells are filled first.
