5. Aluminium (Group III) and Silicon Group (IV) are adjacent to each other on the periodic table. Relative to aluminium, silicon is less dense and has a higher melting temperatures, is harder and is very prevalent in sand and rocks. Yet, aluminium has more mechanical applications in engineering systems while Si finds more applications in electronic systems Explain how the functional properties of these element arise and why they are suited for different functions. 6.
