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.
Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
All noble gases have 8 valence electrons except for?
Helium is the noble gas with only 2 valence electrons
What element is the only noble gas that does not have eight electrons in its outer shell?
Helium is the only noble gas that does not have eight electrons in its outer shell. It has only two electrons in its outer shell.
What noble gas doesn't have 8 valence electrons it only has what?
He does not have 8 valence electrons. It has only 2 valency electrons.
What noble gas has 2 electrons?
helium
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
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 a noble gas have?
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.
How many electron does a noble gas have in its last shell?
Helium has 2 electrons in its last (and only) shell. All other noble gases have 8 electrons in its valence shell.
How does helium differ from the other elements in its family noble gases?
Helium differs from other noble gases in its smaller atomic size and lower atomic mass. It is also the only noble gas that does not have a full shell of electrons, containing just 2 electrons in its outer shell. Additionally, helium is the least reactive of the noble gases due to its stable electron configuration.
