There is only one electron inhabiting hydrogen and the compound therefore only has one shell, effectively making that shell the outer shell.
TL;DR
There is 1 electron in the outer shell of hydrogen.

How many valence electrons do the insert gases have?
Enough to fill the outer-most shell. For most this is eight, but for helium it is two.
How many valence electrons will beryllium gain or lose to fill its outer shell?
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
How many number of electrons to fill the outer shell of carbon?
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
How many electrons are needed to fill up carbons outer shell?
4 to fill the 2p shell
How many electrons do the noble gases have in there outer energy levels?
8, with the exception of helium which has 2.
Does helium have a complete outer shell?
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.

What two atoms will have their outer energy level filled with two electrons?
Hydrogen and Helium both only need two valence electrons to fill their outer shell.
How many electrons are needed to fill carbon outer shell?
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
How many electrons does nitrogen require to fill its outer shell?
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
How many valence electrons will beryllium gain or lose to fill its outer shell?
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
If carbon has four electrons in its outer shell does it completely fill its outer selectron shell?
Yes. Two of the electrons will go into the carbon's outer s shell (2s) to completely fill it (s orbitals can contain up to two electrons) and the remaining two will go into its outer p shell (2p).
How many number of electrons to fill the outer shell of carbon?
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
How many electrons would be needed to fill its outer shell for carbon?
4 to fill the 2p shell

4 to fill the 2p shell
How many electrons do the noble gases have in there outer energy levels?
8, with the exception of helium which has 2.
How many electrons does it take to fill the outer shell to become like a noble gas?
For most elements, a complete outer shell, like that of a noble gas, has eight electrons. There are exceptions. Helium, which is the most noble of the noble gases, has only two electrons in its outer shell. A few other light elements only need two (and hydrogen can also exist with no electrons at all, in the form of a naked proton, which is also a form of completion for the outer shell).
