Gain two electrons to have the electron configuration as Argon
To obtain the nearest noble gas configuration, calcium must lose two electrons. This makes Calcium a dipositive ion and it attains the electronic configuration of Argon.
Lithium must lose one electron to attain the configuration of the noble gas, helium
Group 16 elements have 6 valence electrons and they need 2 more electrons
By gaining, losing or sharing electrons and forming chemical bonds / compounds
It must gain two electrons, to form the sulfide ion, S2- In doimg this it attains the electronic configuraion of argon.
It should gain one electron
sulfur has to gain two electrons
nitrogen should give 5 electrons (or better gain 3 electrons) to attain noble gas configuration.
Sulfur must lose six electrons to attain noble gas electron configuration (in SO3, H2SO4 etc) but in most of the compounds it will exist as sulphides which is formed when sulphur will gain two electrons.
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.
aluminium should lose three electrons to attain noble gas configuration
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
Phosphorus should gain 3 electrons and form P3- ion to attain a noble gas configuration
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.
nitrogen should give 5 electrons (or better gain 3 electrons) to attain noble gas configuration.

three
aluminium should lose three electrons 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.
two electrons lost
Krypton is a noble gas and need not lose electrons. It is already stable.
true, just not for Boron witch tries to gain 6 electrons for a stable arrangement
