What element has a stable 2 valence electrons?
The element with a stable 2 valence electrons is helium. Helium has a full outer electron shell with 2 electrons, making it very stable and unreactive.
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.
Which element has the fewest valence electrons?
Helium has the fewest valence electrons, with only 2 valence electrons.
What element has one valence electron but is not a metal?
There is no non-metal with one valence electron. Every element with 1 valence electron belongs to the alkali metals family
How many valence electrons does He have?
Helium has 8 valence electrons. It is a noble gas. none = 0
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)

What element have the same valence electrons as neon?
Argon(Ar) and Helium(He)
What element has a stable 2 valence electrons?

What element whose valence electrons is full with two electrons on the periodic table?
Helium
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.
Which element has the fewest valence electrons?
Helium has the fewest valence electrons, with only 2 valence electrons.
Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
What is the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
An element that does not require eight electrons for a full set of valence electrons is represented by the element symbol B. Boron only needs six electrons to complete its valence shell and achieve stability.
