Calcium is in group 2 of the Periodic Table, meaning that it has 2 electrons in its (outer) valence shell. So it 'only' has to lose those 2 electrons from that to acquire Argon's noble gas structure Ar(2,8,8)
Ca(2,8,8,2) --> Ca(2,8,8,0)2+ + 2e-

How many atoms does a phoshorus atom need to attain a noble gas configuration?
Phosphorus should gain 3 electrons and form P3- ion to attain a noble gas configuration
Is the elecron configuration of an atom related to its tendency to give up or gain electrons during a chemical reaction?
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.
