it must gain (or share) two electrons
It should loose 2 electrons to become a noble gas.
All should lose 2 electrons to attain the nearest noble gas configuration
aluminium should lose three electrons to attain noble gas configuration
Magnesium (Mg) has 12 electrons. To attain a noble gas configuration, Mg would need to lose 2 electrons to have the same electron configuration as a noble gas (like neon). This would result in Mg forming a +2 ion.
Krypton is a noble gas and need not lose electrons. It is already stable.

Atoms lose or gain or share electrons and tend to attain noble gas configuration
Krypton is a noble gas and need not lose electrons. It is already stable.
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.
Calcium loses two electrons to obtain a noble-gas electron configuration.
Phosphorus should gain 3 electrons and form P3- ion to attain a 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.
nitrogen should give 5 electrons (or better gain 3 electrons) to attain noble gas configuration.
No! oxygen does not react with a noble gas because a noble gas does not want any electrons. This means, it's outer shell or valence shell is filled with electrons.
