hydrogen (H) and helium (He)
What else can I help you with?
Is it possible for there to be only one electron in the first orbit and three in the second orbit?
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.
How many shells do the 4th period elements have?
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.
Why does an atom with only one electron in its valence shell make a better conductor than an atom with seven electrons in its valence shell?
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.
How many shell do 2 electrons need?
Only one. The first shell can have up to 2 electrons.
What is the electron shell diagram for helium?
Helium has one energy shell with only 2 electrons in it.

How an insulator work?
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.

How many shell do 2 electrons need?
Only one. The first shell can have up to 2 electrons.
What is the electron shell diagram for helium?
Helium has one energy shell with only 2 electrons in it.
What is the Valence electron in He?
helium has only one shell with two electrons and can be considered to be as the valence electrons.
How many electrons fill the outer shell of helium?
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 spaces are in the valence shell of helium?
Helium has only one shell with a total of 2 electrons.
How many electrons can occupy a single orbit?
Electrons orbiting an atomic nucleus do not do so like planets round the sun, they do so in shells round the nucleus.Each electron shell can accommodate 2n2 electrons, i.e. the first shell can accommodate 2 electrons, the second shell 8 electrons, the third shell 18 electrons, etc.Electrons always fill the smallest shells (nearest the nucleus) first as this is the lowest energy configuration.The shells do not have to be full - for instance a hydrogen atom has just one electron and thus the first shell has only one electron in it not two.It is possible to push an inner electron up into a higher shell (by providing energy) if there is a vacancy - however it will fall back and when it does so it will emit a photon of light this is why things glow when they get hot.
Does hydrogen contain 2 electrons in the first shell?
No. Hydrogen has only one
How many electrons are in the outermost shell for hydrogen?
Only one electron exist.
