Helium has only two valence electrons. All other noble gases have 8 valence electrons.
Yes, helium, xenon, and neon all have stable electron configurations. Helium has a full outer electron shell with 2 electrons, xenon has a full outer shell with 8 electrons, and neon has a full outer shell with 8 electrons as well.
Helium is a noble gas with a full outer electron shell, making it stable and unreactive. Its electron configuration is already stable, so it has little tendency to gain, lose, or share electrons with other elements to form chemical bonds. This inertness is why helium does not readily react with other elements.
The ground state electron configuration of hydrogen is 1s^1, meaning it has one electron in the 1s orbital. Helium in its ground state has an electron configuration of 1s^2, indicating it has two electrons in the 1s orbital. So, the main difference is that hydrogen has one electron in its outer shell while helium has two electrons in its outer shell.
Helium is not an electron donor or acceptor as it has a full outer electron shell (2 electrons). It is classified as a noble gas and is chemically inert, meaning it does not readily form chemical bonds.
Helium has a stable electron configuration with a full outer shell, making it non-reactive and safe to use in airships. In contrast, hydrogen has a single electron in its outer shell, making it highly reactive and prone to combustion in the presence of oxygen, posing a safety risk in airships.
The outer electron orbits of helium, neon, and argon are all filled with electrons, making them stable and inert. This results in these elements having very low reactivity and being part of the noble gases group on the periodic table. Helium has 2 electrons in its outer orbit, neon has 8, and argon has 18.
Helium(He)
Yes, helium, xenon, and neon all have stable electron configurations. Helium has a full outer electron shell with 2 electrons, xenon has a full outer shell with 8 electrons, and neon has a full outer shell with 8 electrons as well.
2 valence electrons for helium (helium has only 1 shell)
No, helium is not reactive because it is a noble gas and has a full outer electron shell, making it very stable. In contrast, argon is also a noble gas and is not reactive due to its full outer electron shell.

There are 8 electrons in the outer level of all the noble gases except helium. This full outer level gives them stability and makes them less reactive. Helium, as a noble gas, has only 2 electrons in its outer level.
No, helium exists as He, with a single electron in its outer shell. The H2 molecule refers to two hydrogen atoms bonded together.
2.You are in terrible need of a periodic table. It's really not that difficult, and it's well worth learning.
