Effect of Atomic Size on the Isothermal Bulk Modulus and Surface Tension of Liquid Metals

The isothermal bulk modulus $$K_{{T_{m}}}$$ and surface tension γm of liquid metals at the melting point increase with decreasing atomic size a, these dependences are similar to one another. It is shown that transition a hexagonal closed-packed body-centered cubic structure concentrated above γm− regression line, face-centered below this line. In alkali, alkaline earth, rare earth metals, change in increases several times more intensively than metals. reduced quantities have been introduced. demonstrates high coincidence parameter a−2, a−3. ratio product γm×(a )−1 compares energy atoms on bulk.
