∙ 12y agoValence electrons are the electrons present in the outermost orbital of an atom.now since the helium has electronic configuration of 1s2 hence it's valence electrons are 2.

∙ 7y agoHelium has 2 valence electrons, but rarely uses them for bonding. It has a total of two electrons, completing its valence shell, making it extremely stable (almost unreactive).

How many valence electrons does He have?
Helium has 8 valence electrons. It is a noble gas. none = 0
In group 8 on the Periodic Table what element does not have 8 valence electrons?
Helium. It has 2 electrons in its single shell.
How many electrons are there in the valence shell of a nitrogen atom?
Nitrogen has 5 valence electrons. Its atomic number is 7 therefore it has a total of 7 electrons. If you put this in a Bohr-Rutherford Diagram, there would be 2 electrons in the first shell (Helium structure) and 5 electrons in the outer shell. The number of electrons in an element's outermost shell is its number of valence electrons.
What element is nonreactive but only has 2 valence electrons?
Helium, it is the most inert gas (element ) of all.
What do elements in families have in common?
they all have the same amount of valence electrons. Except with group 18 they all are the same except for Helium which has 2 valence electrons.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
