Radius of hydrogen
WebThe hydrogen atom consists of a proton and an electron with an atomic radius of 0.37 Å. Hydrogen ions are formed either by accepting an extra electron from an atom (which is more electropositive than the hydrogen) or donating the only electron to the atom (which is more electronegative than the hydrogen). In these cases, an ionic bonding is ...
