why is the Aluminium bioling point higher than silicon? And why is silicon's meltingpoint higher than aluminium?
Answers
Explanation:
Boiling point increases as you go from left to right across the periodic table. This is because there is an increased force of attraction as you go across the elements. The boiling point for elemental Aluminum is 4,478°F (2,470°C) and 5,909°F (3,265°C) for elemental Silicon.
Silicon has high melting and boiling points because it is a giant covalent structure. You have to break strong covalent bonds before it will melt or boil.

Answer:
Silicone have high melting point and lower broiling point
Explanation:
It's because when silicone melts its remaining bond is metallic as we know that silicone is semi metal. Now it's metallic bond formed is weaker than Aluminum because aluminum is pure metal and has more free electrons in surrounding while silicone in comparison have less so it has weak metallic bond as compared to aluminum
