Not by itself, no (that is, hydrogen is not a noble gas). A neutral hydrogen atom starts out with 1 electron, but it needs 2 electrons to fill its shell. Therefore, a hydrogen atom will often form 1 covalent bond with another atom, in order to gain that 1 extra electron it needs to fill its shell.
Important note: Most elements need 8 electrons to get a full shell, but hydrogen is the exception: it only needs 2 electrons to get a full shell.

Lewis dot diagram for helium?
He :The number of electrons in an atom's outer electron shell determines how many dots there are. Helium has 2 electrons in its outer electron shell, so 2 dots.
Does Phosphorus have a complete outer shell?
No, it doesn't have a complete octet. Phosphorous is in group 5A, meaning it has 5 valence electrons (5 electrons on its outest shell).
What is the formula for iodide ion?
I-1 It is Iodine with an electron added to complete the outer shell.
Nitrogens outer shell?
hello it has 5 electrons on the outer shell
Chlorine will tend to lose all of its seven outer electron or gain one electron?
It would gain or share an electron - in order to complete the outer shell.
Why Helium will not react with anything because it has a complete outer electron shell?
Normally, when elements react they do so to attain a full outer shell, which is stable. Helium already has a full outer shell and so does need to not react to attain one.
What type of bond would likely form with Helium and Helium atoms?
No bond at all, He has a complete outer shell
What is the atomic number of helium's outer shell?
The outer shell of helium does not have an atomic number, that number belongs to helium itself whose atomic number is 2.
How many electrons are in the outer shell of helium?
2 valence electrons for helium (helium has only 1 shell)
How many electron are in the outer shell of helium?
2 valence electrons for helium (helium has only 1 shell)
What 3 elements on the periodic table had complete outer shells?
All the Noble/Inert gasses. However, Helium (He) has a complete outer shell of only TWO(2) electrons. The other noble gases all have a complete octet (outer) shall, of EIGHT(8) (Octet) electrons.
What a description for helium?
helium is noble gas has atomic number is 2. it don't react with any other element because outer most shell is complete.
How many electrons does He and Ca have in its outer shell?
Helium (He) has 2 electrons in its outer shell. Calcium (Ca) has 2 electrons in its inner shell and 8 electrons in its outer shell.
Why is helium such a stable element?
Its outer electron shell is complete, with 2 electrons. Therefore it does not readily bond with other elements.
Why is Helium considered a stable element?
Under normal conditions Helium will not react with anything because it has a complete outer electron shell.
How many electrons does helium has in its outer shell?
2
Why are least reactive elements not so reactive?
The least reactive elements are the noble gases (helium, neon, krypton, argon, xenon). They each have a complete outer electron shell (two electrons for helium, eight electrons in the outer shell of the other noble gases). Chemical reactions take place in ways that result in making outer electron shells more complete (or for transition state elements, it can also make inner shells more complete), so if the outer electron shell is already complete, there is no basis for a chemical reaction.
