It will vary depending on the noble gas.
helium has 2, neon has 10, argon has 18, krypton has 36, xenon has 54, radon has 86.

A noble gas typically has 8 electrons, except for helium which has 2 electrons. They have a full outer electron shell, making them stable and unreactive.

∙ 12y agoNoble Gasses will not form ions because they already have full shells of electrons, so the proton to electron ratio is 1:1.

How many electrons does O need to achieve noble gas?
Oxygen needs to gain 2 electrons to achieve a stable octet, like a noble gas.
How many electrons must be gained or lost for Mg to attain a noble gas?
Mg must lose 2 electrons to attain the electron configuration of a noble gas (in this case, Neon).
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.
What element is a noble gas and has 36 electrons?
Krypton is a noble gas with 36 electrons.
Does a noble gas have twice as many electrons as protons?
equal numbers of protons and electrons
How many electrons does O need to achieve noble gas?
Oxygen needs to gain 2 electrons to achieve a stable octet, like a noble gas.
How many electrons must be gained or lost for Mg to attain a noble gas?
Mg must lose 2 electrons to attain the electron configuration of a noble gas (in this case, Neon).
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.
What element is a noble gas and has 36 electrons?
Krypton is a noble gas with 36 electrons.
How many electrons must be gained or lost by each element to achieve a noble gas configuration of electrons for oxygen?
Oxygen needs to gain 2 electrons to achieve a noble gas configuration, as it has 6 valence electrons and wants a full valence shell of 8 electrons, like a noble gas.
How many valence electrons are in the noble gas neon?
8.
How many electrons does strontium have to give up achieving a noble gas electron configuration?
Strontium has 38 electrons. It needs to give up 2 electrons to achieve a noble gas electron configuration, similar to the nearest noble gas, which in this case is krypton (36 electrons).
How many electrons does As to gain noble gas configuration?
it should gain 3 electrons
Does a noble gas have twice as many electrons as protons?
equal numbers of protons and electrons
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 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 I have to gain to become noble gas?
It has 7 valence electrons, so needs 1 more to become noble.
