hydrogen (H) and helium (He)
No, according to the Aufbau principle, the first orbit (K shell) can only hold a maximum of 2 electrons and the second orbit (L shell) can hold a maximum of 8 electrons. This is due to the way electrons fill orbitals in an atom based on their energy levels.
Every element in the first period has only one orbit. This means that they can have only a duplet in their valence shell, which happens to be their only electronic shell. The elements included in the first period are Hydrogen and Helium.
Only one. The first shell can have up to 2 electrons.
An atom with only one electron in its valence shell is more likely to lose that electron easily, making it a better conductor. In contrast, an atom with seven electrons in its valence shell is more stable and less likely to lose electrons, thus making it a poor conductor.
Helium has one energy shell with only 2 electrons in it.

All atoms have electrons that orbit the nucleus, we are concerned with the outermost orbit. The outer orbit shell can have from 1 to 8 electrons. The fewer electrons an atom has in this orbit the better it is at conduction (one or two electrons, it is easy to knock one of the electrons out of orbit and pass to the next atom). The more electrons you have, the better it is at insulating. Nothing is a perfect insulator, if you apply enough voltage the electrons will move (current will flow). This is why the insulation on conductors have a voltage rating.

helium has only one shell with two electrons and can be considered to be as the valence electrons.
Helium has one energy shell with only 2 electrons in it.
Helium has only one shell with a total of 2 electrons.
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.
Only one electron exist.
Only one electron for hydrogen.
No. Hydrogen has only one
