No. Free electrons are not stable.
Aron is nonreactive because it has no free electrons it is stable and even as it is a noble gas.
A stable sodium atom has 11 electrons.
Mg is a metal and does not need the electrons it donates two electrons and becomes stable.
Metals will LOSE electrons to become stable.
they are stable
The valence electrons are the outermost electrons. In an atom, its lower energy levels have been filled and are therefore stable. But, except for the noble gases, the valence energy level is not filled, and therefore not stable. So atoms must undergo chemical reactions in order to fill their valence shells and become stable. They can do this by sharing electrons, transferring electrons, or by forming a sea of electrons shared by all the atoms.
No. Argon has completely filled orbitals and is stable. So it is non conductive due to the absence of free electrons.
when the shells have complete electrons they are stable
It is stable when filled with electrons.
It's stable with 42 neutrons 33 protons and electrons although normally it has 3 extra electrons but it's stable
Sulfur gains 2 electrons to become stable.
The process of losing or gaining electrons to become stable is called ionization.
