A neutral atom of nitrogen (atomic number 7) needs to lose 3 electrons to have a full valence electron shell, similar to the nearest noble gas neon. This is because nitrogen has 5 valence electrons and needs 8 electrons in its outer shell to achieve stability.
Lithium is in group 1 of the Periodic How_many_electrons_must_the_lithium_atom_give_up_to_become_stable, so it must lose one electron for it to attain a full outermost energy level and become stable.The charge will then be positive (+).
Sulfur has six valence electrons and can therefore attain an inert gas configuration in two different ways: by accepting two electrons to attain the electron configuration of argon or donating or sharing six electrons to attain the electron configuration of neon. In combination with the much less electronegative element sodium, sulfur accepts one electron from each of two sodium atoms to form the ionic compound Na2S, but in combination with the more electronegative element fluorine, sulfur shares its six valence electrons with each of six fluorine atoms to form six polar covalent bonds with fluorine.
Iodine, located in Group 17 of the periodic table, has 7 valence electrons. To achieve a noble gas electron configuration (like Xenon), it must gain 1 electron to fill its valence shell and attain stability.
iodine has 7 electrons in the valence shell. and needs one more electron to attain stable noble gas configuration. So it gains one electron and forms iodide ion with charge of -1.
nitrogen should give 5 electrons (or better gain 3 electrons) to attain noble gas configuration.
A nitrogen atom needs to gain 3 electrons in order to attain a noble-gas electron configuration, similar to that of neon. This would allow the nitrogen atom to fill its outermost energy level and achieve greater stability.
Calcium's electron configuration is [Ar] 4s2. To attain a noble gas configuration, calcium must lose 2 electrons to have the same electron configuration as argon, 4s2 3d10.
Calcium loses two electrons to obtain a noble-gas electron configuration.
Calcium (Ca) has 20 electrons and its electron configuration is [Ar] 4s². To attain a noble gas electron configuration, calcium needs to lose two electrons to achieve the stable electron configuration of argon ([Ar] 4s² 3d¹⁰).
Metals like sodium,potassium get noble gas configuration by losing electrons. Elements like nitrogen,oxygen get noble gas configuration by gaining electrons. Halogens get noble gas configuration by sharing electrons.
It loses 2 electrons and becomes a +2 ion.

Sulfur gains two electrons to attain a noble gas configuration, which is the electron configuration of argon. This allows sulfur to have a stable octet of electrons in its outer shell and achieve a more stable electron configuration.
aluminium should lose three electrons to attain noble gas configuration
To attain a noble gas electron structure, a nitrogen atom must gain three electrons, not lose five. Nitrogen is in group 15, so it has five valence electrons. By gaining three electrons, it can achieve a stable octet like the noble gas neon.
Calcium (Ca) has 20 electrons in its neutral state. To attain a noble gas electron configuration (like argon), calcium would need to lose 2 electrons to have the same electron configuration as argon, as argon has 18 electrons.
