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 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 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.


How many shell do 2 electrons need?

Only one. The first shell can have up to 2 electrons.


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.


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.


What is the electron shell diagram for helium?

Helium has one energy shell with only 2 electrons in it.


How many spaces are in the valence shell of helium?

Helium has only one shell with a total of 2 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 electrons are in the outermost shell for hydrogen?

Only one electron exist.


How many electrons on their outer shell does hydrogen have?

Only one electron for hydrogen.


Does hydrogen contain 2 electrons in the first shell?

No. Hydrogen has only one
