Examples (in the sense of non-radiactive): helium, oxygen, fluorine, argon, lanthanum, hafnium lithium etc.
A completley filled out electron level makes the atom stable
A monatomic molecule contains only one atom. It is a single atom that is chemically stable. Examples include noble gases like helium and neon.
An aluminum atom has three valence electrons and needs to give up all three to achieve a stable electron configuration similar to that of a neon atom, which has a full octet of eight valence electrons. By losing these three electrons, aluminum attains a stable, positively charged ion (Al³⁺), resembling the noble gas configuration of neon.
Sodium has 11 electrons.
A stable atom of Zinc (Zn) typically has 34 neutrons.
The most stable carbocation is the tertiary carbocation, which has three alkyl groups attached to the positively charged carbon atom.
A completley filled out electron level makes the atom stable
An atom becomes stable by gaining or loosing electrons.
A monatomic molecule contains only one atom. It is a single atom that is chemically stable. Examples include noble gases like helium and neon.
The most stable atom in the periodic table is helium.
An aluminum atom has three valence electrons and needs to give up all three to achieve a stable electron configuration similar to that of a neon atom, which has a full octet of eight valence electrons. By losing these three electrons, aluminum attains a stable, positively charged ion (Al³⁺), resembling the noble gas configuration of neon.
Nitrogen is a diatomic molecule, meaning it exists naturally as N2 because it is more stable when bonded to another nitrogen atom. Each nitrogen atom in the molecule shares three pairs of electrons with the other nitrogen atom, resulting in a stable molecular structure.
Sodium has 11 electrons.
An atom with five valence electrons can achieve a full set of eight valence electrons by either gaining three electrons (to reach a stable octet) or losing three electrons to have a stable arrangement. This would result in the atom forming an ionic bond, such as in the case of boron transferring three electrons to become the boride ion.
When the atom has 8 valence electrons.
0 in elemental form +3 in most of its stable compounds
Yes, the chlorine atom is stable. It has a full outer electron shell with 8 electrons, making it a highly reactive and stable element.
