WebDec 15, 2024 · H+ is just a proton, so no electrons would be present. In covalent bonding, the electrons that form the covalent bond do not have to come from each atom. There … WebHelium is the smallest and the lightest noble gas and one of the most unreactive elements, so it was commonly considered that helium compounds cannot exist at all, or at least under normal conditions. Helium's first ionization energy of 24.57 eV is the highest of any element. Helium has a complete shell of electrons, and in this form the atom does not … jovy watermelon slices
