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.
This is because in nitrogen the 2p subshells are filled by 3 electrons which is half filled electronic configuration. But oxygen has to lose an electron to attain the half filled electronic electronic configuration. Hence nitrogen is more stable than oxygen.
two electrons lost

It is more likely that Nitrogen will attempt to gainelectrons to fill its outer shell and attain a noble gas stucture.
nitrogen should give 5 electrons (or better gain 3 electrons) to attain noble gas configuration.
Nitrogen has 5 valence electrons. It needs three more to attain noble gas configuration (of that of neon)
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.
Since nitrogen is a non-metal with five electrons in its valence shell, it will gain three electrons to attain a stable electronic configuration. So its valency is -3.

Atoms lose or gain or share electrons and tend to attain noble gas configuration
Yes. If there are 1 to 3 valence electrons in an atom, then generally those elements will lose these electrons to attain noble gas configuration. If there are 5 to 7 valence electrons, then generally those elements will gain electrons to attain noble gas configuration.
To attain the noble gas configuration, Ca would have to lose 2 electrons, Mg would have to lose 2 electrons, Ba would have to lose 2 electrons, and Be would have to lose 2 electrons.
Phosphorus should gain 3 electrons and form P3- ion to attain a noble gas configuration
This is because in nitrogen the 2p subshells are filled by 3 electrons which is half filled electronic configuration. But oxygen has to lose an electron to attain the half filled electronic electronic configuration. Hence nitrogen is more stable than oxygen.
two electrons lost
true, just not for Boron witch tries to gain 6 electrons for a stable arrangement
