FranHelium is more stable than hydrogen because it has a full valence shell with 2 electrons, following the octet rule. Hydrogen only has 1 electron in its valence shell and is less stable due to its incomplete shell. Additionally, the helium atom has a lower potential energy, making it more stable.

What occurs when Hydrogen is turned into helium?
Hydrogen undergoes nuclear fusion to form helium in a process that releases a large amount of energy. This process is the main source of energy for stars, including our Sun. The newly formed helium atom is more stable than the original hydrogen atoms.
How is helium atom different from a hydrogen atom?
Helium has a nuclear charge of +2 and 2 electrons in a 1s orbital. Hydrogen has a nuclear charge of +1 and just one electron in a 1s orbital. The extra charge on the nuclees means that the electrons in He are more tightly bound than in hydrogen thuis reflected in the ionization energy of 2372 kJ/mol for He and about 1312 kJ/mol for hydrogen. For helium t the "outer shell" is full, a "stable " configuration.
Is hydride ion more stable or less stable than H-atom?
The hydride ion (H-) is more stable than the hydrogen atom (H•) because the extra electron in the hydride ion helps to stabilize the negative charge through electron-electron repulsion. Additionally, the hydride ion benefits from a full electron octet, making it more stable compared to the hydrogen atom, which has an unpaired electron.
What has more mass hydrogen or helium?
Helium has more mass than hydrogen. Helium is composed of two protons and two neutrons, while hydrogen is a single proton.
Is a helium atom larger than a neon atom?
helium as it contains 2 protons, while hydrogen only contains 1. Additionally, the orbit of the 2 electrons in a neutral helium atom would also be larger than the orbit of the single electron in hydrogen.
