What else can I help you with?
Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
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.
What information is given by the noble gas notation Ne 3s2?
The element is magnesium with an atomic number 12.The element belongs to the 3rd period, with two valence electrons in the s orbitals. The element is an example of alkaline earth elements or group 2 elements.
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.
When this element gains 2 electrons it has the electron configuration of the noble gas Argon?
The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
Helium is what type of element?
Helium is a noble gas with 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.
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 is the noble gas element helium differ from radon?
Helium has 2 electrons and Radon has 86 electrons but both have 8 valence electrons (8 electrons in their outermost shells)
How many electrons will Strontium gain or lose in forming a noble gas configuration?
Strontium, a group 2 element, will lose 2 electrons to attain a noble gas configuration because it will achieve a stable electron configuration similar to the nearest noble gas, which is krypton. Strontium has 38 electrons in its neutral state, while krypton has 36 electrons. By losing 2 electrons, Strontium becomes Sr2+, and its electron configuration is similar to krypton.
What element is nonreactive but only has 2 valence electrons?
The element that fits this description is helium. Helium is a noble gas with a full outer shell of 2 electrons, making it stable and nonreactive under normal conditions.
What noble gas has 2 electrons?
helium
