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 O need to achieve noble gas?
Oxygen should gain 2 electrons to achieve noble gas configuration
How many electrons does it take to fill the outer shell to become like a noble gas?
For most elements, a complete outer shell, like that of a noble gas, has eight electrons. There are exceptions. Helium, which is the most noble of the noble gases, has only two electrons in its outer shell. A few other light elements only need two (and hydrogen can also exist with no electrons at all, in the form of a naked proton, which is also a form of completion for the outer shell).
How many electrons does N need to be noble gas?
An atom of nitrogen needs 3 more electrons to achieve a stable, noble gas electron configuration. This would give nitrogen a total of 8 valence electrons, making it isoelectronic with a noble gas (in this case, neon).
How many electrons does sulfur need to lose to become a noble gas element?
Sulfur has six valence electrons and is in group 16 of the periodic table. To achieve a stable noble gas configuration, it needs to lose two electrons, resulting in a positive charge of +2, similar to the electron configuration of neon. This loss allows sulfur to attain a full outer shell, characteristic of noble gases.
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 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 must be lost Ca to attains a noble gas electron?
Calcium (Ca) has 20 electrons in its neutral state. To attain a noble gas electron configuration (like argon), calcium would need to lose 2 electrons to have the same electron configuration as argon, as argon has 18 electrons.
How many electrons does O need to achieve noble gas?
Oxygen should gain 2 electrons to achieve noble gas configuration
How many valence electrons do most elements need to become stable?
8 valence electrons are needed for an element to become stable, which is why the noble gases do not interact with any other elements. They are already stable. However, the exception is Helium, the first noble gas, which only has two valence electrons. 8 valence electrons are needed on the 2nd and 3rd valence shells for any molecule to become stable.

Helium, which is the most noble of the noble gases, has only two electrons in its outer shell.

How many electrons does sodium need to lose to become a noble gas element?
Sodium would need to lose one electron in order to obtain a full and stable outer shell, however it would be an ion with a positive charge
How many electrons does carbon have to give up to achieve a noble gas configuration?
4 but it will need energy, so carbon gain 4 electrons to achieve a noble gas configuration.
How many electrons does N need to be noble gas?
An atom of nitrogen needs 3 more electrons to achieve a stable, noble gas electron configuration. This would give nitrogen a total of 8 valence electrons, making it isoelectronic with a noble gas (in this case, neon).

Sulfur has six valence electrons and is in group 16 of the periodic table.

This loss allows sulfur to attain a full outer shell, characteristic of noble gases.
How many electrons does n need to gain to becom isoelectronic with a noble gas?
An atom with atomic number n needs to gain enough electrons to have the same number of electrons as the nearest noble gas in the periodic table. This would typically involve gaining 8 electrons to achieve the stable electronic configuration of a noble gas.
How many electrons would calcium have to give up to achieve a noble-gas configuration?
Calcium has to lose 2 electrons to form noble gas configuration.
