摘要: A simple model is used for estimating of the bottom energy electron conduction band and electron-forbidden gap energy. It shown that electrons in fluid hydrogens are localized not bubbles, as was considered previously, but molecular negative ions surrounded by voids about 0.5 nm radius. The conductivity at very high pressures connected to transfer positively charged clusters negatively bubbles. As pressure density increase, dissociation occurs localization on atoms becomes more favorable, also with creation a void around atomic ions. At sufficiently concentration atoms, probability tunnel transition an from one atom another closed unity, levels degenerate band, caused these quasifree electrons. supposed this charge mechanism may play important role region metallization.
