Web21 de set. de 2024 · Why potassium melting point is low? -Decrease in atomic size leads to stronger bonds between the atoms of the metals. As a result more energy is required to break these bonds and cause them to melt. Thus, aluminium has a higher melting point than sodium. Thus, sodium and potassium have lower melting points than aluminium. WebMetals tend to have high melting points and boiling points suggesting strong bonds between the atoms. Even a soft metal like sodium (melting point 97.8°C) melts at a considerably higher temperature than the …
