What is a noble gas but does not have 8 valence electrons?
Helium is the only noble gas that doesn't have 8 valence electrons. It only has 2.
You are a noble gas with 2 electrons?
Helium
How many electrons does O need to achieve noble gas?
Oxygen should gain 2 electrons to achieve noble gas configuration
Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
How many electrons must be gained or lost for Mg to attain a noble gas?
It should loose 2 electrons to become a noble gas.
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 barium have to give up in order to achieve a noble gas electron configuration?
Barium has 2 electrons in its outer shell. In order to achieve a noble gas electron configuration it needs to lose these 2 electrons. This will leave it with the same electron configuration as Xenon, a noble gas.
What is the noble gas with only 2 electrons?
helium
What element has noble gas with 2 electrons?
helium
How many electrons does barium has to give up to achieve a noble gas electron configuration?
Barium has 2 valence electrons. It needs to give up these 2 electrons to achieve a noble gas electron configuration, specifically by having a filled outer shell like a noble gas.
Does group 2A gain electrons or lose electrons in order to achieve a noble gas configuration?
loses 2 electrons to achieve a noble gas configuration
