Answer When the outermost shell(valence shell) is filled the atom is to be most stable.
First Shell: holds up to 2 electrons
Second Shell: holds up to 8 electrons
Third Shell: holds up to 18 electrons
Fourth Shell: holds up to 32 electrons
The most stable atom in the periodic table is helium.
The most stable carbocation is the tertiary carbocation, which has three alkyl groups attached to the positively charged carbon atom.
The most stable resonance structure for the CNO ion with nitrogen as the central atom is one where the negative charge is on the oxygen atom, and the double bond is between the carbon and nitrogen atoms.
An atom of iodine will most likely gain one electron to form a stable octet in its outer energy level. This will give iodine a full set of 8 electrons, making it more stable and less likely to react with other atoms.
The electron configuration that represents the most chemically stable atom is the noble gas configuration, which is when an atom has a completely filled valence shell. This configuration is stable because it has a full complement of electrons and is unlikely to gain or lose electrons.
The most stable atom in the periodic table is helium.
True
The most stable atom is helium because it has a full outer electron shell, which makes it less likely to react with other atoms.
It becomes most stable when its nucleus is filled, not when it is filling it.
The most stable state of an atom is called the ground state. This is when the electrons occupy the lowest energy levels available to them.
less stable
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
The most stable resonance structure for the CNO ion with nitrogen as the central atom is one where the negative charge is on the oxygen atom, and the double bond is between the carbon and nitrogen atoms.
An atom becomes stable by gaining or loosing electrons.
