All the elements in their normal state are reactive and unstable.
In order to attain stability i.e. a state of minimum energy, they tend to form ions by loosing or gaining electrons. By doing so, they achieve stable electronic configuration or noble gas configuration.
However, some elements do not form ions. Instead of that, two such atoms share electrons with each other and achieve this noble gas configuration.
At the end, the main reason for attaining a noble gas configuration is to attain max. stability and min. energy.

How many electrons must Kr lose to attain a noble gas electron configuration?
Krypton is a noble gas and need not lose electrons. It is already stable.
How many electrons does lithium need to add to satisfy the Octet Rule?
Seven electrons should be added to attain the higher noble gas configuration.
How many electrons do you need to become a noble gas?
A species (element, cation or anion) should have eight valence electrons to have a noble gas electronic configuration. However element upto atomic number 4 may have 2 valence electrons and attain the electronic configuration of helium noble gas.
How many electrons does neon need?
Nitrogen has 5 valence electrons. It needs three more to attain noble gas configuration (of that of neon)
How many electrons does sulfur gain to attain a noble gas configuration?
Gain two electrons to have the electron configuration as Argon
Why is it you need to attain a noble gas configuration?
Because it is energetically favorable
What makes the elements in the halogen group reactive?
they need one more electron to attain noble gas configuration and hence are highly reactive.
