WebWhy is H2 more stable than LiH? Two hydrogen atoms have exactly the same electronegativity. Therefore, H2 is strictly covalent, with 0 dipole moment. Li and H have electronegativities of 0.98 and 2.2 respectively. That’s a difference of 1.22, enough to make LiH a weakly ionic compound with a dipole moment of 6.

H₂ is formed dew to s-s overlapp. Whereas atomic number of helium is 2 . It’s electronic configuration is 1s². Filled orbital can not overlapp and hence cannot form a bond.

Helium-2 or He is an extremely unstable isotope of helium. Its nucleus, a diproton, consists of two protons with no neutrons. According to theoretical calculations, it would have been much more stable (although still undergoing β decay to deuterium) if the strong interaction had been 2% greater. Its instability is due to spin–spin interactions in the nuclear force, and the Pauli exclusion principle, which forces the two protons to have anti-aligned spins and gives the diproton a negati… WebDec 4, 2024 · In He2 (dihelium), the two 1s atomic orbitals overlap to create two molecular orbitals: sigma (1s) and sigma (1s)*.
