It depends on the charge of the atom/ion however in a no-charged state Helium will have 2 electrons. If the Helium is charged negatively will have more. If it is charged possitively (up to 2+) it will have less. As Helium is a noble gas, it is rarely found in a charged state!

Does an atom of helium have eight electrons in its outer energy level?
the largest number of electrons an atom of helium can have is 2, because it is in the first period, which means it can only have one energy level, which has a maximum capacity of two electrons
How many electrons does one atome have in hulim?
Helium's atomic number is 2. Therefore, it has 2 positively charged protons in its nucleus. To balance the total charge then, one atom of helium will also have 2 electrons.

How many electrons does helium has?
Helium has 2 electrons in the 1s orbital. This also means it has 2 valence electrons. For all neutral atoms, the number of electrons is equal to the number of protons (the same as the atomic number). i suggest you get a periodic table.
How many kinds of atoms does helium have?
Helium has one kind of atom: helium.
Which one has the largest atom helium or argon?
Niether. In 2015, the largest known atom belonged to ununoctium.
Does helium have the same amount of valence electrons as the others in its group?
No it does not, there are shells and orbitals that determines how reactive an atom is. Helium has 2 valence electrons, which fill up its entire shell, so it is like a noble gas. the other noble gasses have 8 valence electrons, which fill up their entire shell.
Why does helium atom need only two valance electrons?
because it only has one orbital
