It is not that way. Carbon gains electrons while a chemical reaction to have 8 shells in the outermost orbit. Though it has 4 electrons in the outermost orbit, it usually gains four electrons or shares four electrons while a chemical reaction. eg hydrocarbons methane butane propane.
It doesn't lose or gain
gain
gain 4 electrons:- Because the energy released (electron affinity) for the addition of four electrons is too high, Lose 4 electrons:- energy required to lose electrons (the sum of the first 4 ionization energies) is too high
It will gain an electron so that it can complete a full outer shell of 8 electrons.
Sodium will lose 1 electron in its compounds.
Atom lose electron to form positive ion and some gain electron to form negative ion.
It doesn't lose or gain
gain
Gain of one electron
gain
gain 4 electrons:- Because the energy released (electron affinity) for the addition of four electrons is too high, Lose 4 electrons:- energy required to lose electrons (the sum of the first 4 ionization energies) is too high
gain
As a neutral atom lose an electron then it becomes a positive ion As it gains an electron then it becomes a negative ion
Lose or gain an electron
No. Lithium will lose an electron.
It would gain or share an electron - in order to complete the outer shell.
No. They gain electrons
