Atoms are trying achieve a stable electronic configuration i.e., stable arrangement of electrons in their electron shells. All configurations are not stable. Mostly stable configuration is attained by forming an octet of electrons in outer most shell. Sometimes octet rule is violated also.
Calcium has 2 valence electrons and it typically loses these 2 electrons to achieve a stable configuration.
Yes. The octet rule is a rule of thumb that states that atoms tend for form bonds that allow the bonded atoms to have eight electrons in their valence shells. This is a "driving force" in chemistry, and it explains many, many reactions. Use the link below to gather more information.
Neon has completely filled valence orbitals, obeys octet rule and is hence stable. Chlorine needs one more electron to complete octet and is hence reactive.
This atom must gain 3 electrons to achieve an octet.
Lose two electrons to form a doubly charged calcium cation.
In its ground state it does have a stable octet.
Xenon, like all the noble gases except helium, already has a stable octet!
by losing or gaining electrons to become stable
No. Calcium gains the noble gas configuration (octet) if it loses two electrons and not one.
To achieve octet configuration (stable)

Neither. It has a stable octet in its ground state.
The very simple duet and octet models of covalent chemical bonding describe the chemical bond as involving an electron pair situated between atoms and that atoms lighter than He (there is only H!) achieve a stable duet (2 electrons)-- atoms heavier than He achieve an octet. the duet and octet are the stable configurations of noble gases. Lewis dot diagrams are typically used to "place" the electrons in the appropriate positions.
They can either pick the electrons from around them, or start throwing them off in a measure of radioactivity.
Well according to the octet rule the a compound must have 8 valance electrons to be stable.
eight. it is important to obtain octet so that elements become stable.
