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-
What else can I help you with?
How many valence electron does Ca lose or gain to attain noble-gas electron configuration?
Calcium loses two electrons to obtain a noble-gas electron configuration.
How many electrons will a calcium atom Ca lose in order to get a noble gas configuration?
Calcium will lose two electrons to gain the noble gas configuration of Argon.
How many electrons does sulfur gain to attain a noble gas configuration?
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.
What must oxygen do to electrons to attain noble gas status?
Oxygen must gain two electrons to attain noble gas status, which means having a complete outer electron shell. This would give oxygen a full valence shell, similar to the nearest noble gas, neon.
How many electrons does nitrogen give up to achieve noble gas electron configuration?
nitrogen should give 5 electrons (or better gain 3 electrons) to attain noble gas configuration.
How many valence electron does Ca lose or gain to attain noble-gas electron configuration?
Calcium loses two electrons to obtain a noble-gas electron configuration.
How do you get a noble gas configuration?
Atoms lose or gain or share electrons and tend to attain noble gas configuration
How many electrons will a calcium atom Ca lose in order to get a noble gas configuration?
Calcium will lose two electrons to gain the noble gas configuration of Argon.
How many electrons does sulfur gain to attain a noble gas configuration?
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.
What must oxygen do to electrons to attain noble gas status?

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.
How many electrons does a carbon atom need to gain in order to attain a noble gas electron configuration?
4
How many electrons does nitrogen give up to achieve noble gas electron configuration?
nitrogen should give 5 electrons (or better gain 3 electrons) to attain noble gas configuration.
How many electrons does group 6A need to gain to become a noble gas?
They should gain 2 electrons to attain noble gas electronic configuration. (it doesn't become a noble gas as the number of protons are not same)
How many electrons does silicon need to gain a noble electron gas configuration?
An atom of silicon needs to gain 4 electrons in its 3p sublevel to attain the noble gas electron configuration of argon, the noble gas in period 3 of the periodic table.
How many electrons does a nitrogen atom need to gain in order to attain noble-gas electrons 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.
