Germanium is a chemical silver-white metalloid chemically similar to tin. It is an important semiconductor material used in transistors. It is named after the country of Germany. Aluminium is a silvery white and ductile member of the boron group of chemical elements. Aluminium is resistant to corrosion. Aluminum structural components are vital to the aerospace industry and very important in other areas of transportation and building.

Difference of a steel carabiner and aluminum carabiner?
The main difference between steel and aluminum carabiners is their strength and weight. Steel carabiners are stronger and more durable, making them suitable for heavy-duty and high-stress activities. On the other hand, aluminum carabiners are lighter in weight, more versatile, and better suited for activities where weight savings are important.
What is the binary compound of AlCl?
AlCl3Although a metal-nometal compound, AlCl3 is not ionic (as might be predicted). Single covalent bonds form between aluminum and three chlorine atoms, forming AlCl3 molecules. Two of these join together (forming a 'dimer') with formula Al2Cl6. Aluminium bromide and aluminum iodide are similar in nature. However, aluminum fluoride is ionic. Why the difference in bonding? It all has to do with the difference in electronegativity of the elements:Al & F - difference of 2.37Al & Cl - difference of 1.55Al & Br - difference of 1.35Al & I - difference of 1.05Generally, if the difference in electronegativity is greater than 2.0 then the bond will be ionic. If less than 2.0, then the bond will be covalent.
What is the difference between potassium and aluminum?
potassium belongs to group 1 and has one valence electron. aluminium belongs to group 13 and has three valence electrons.
Is AIF3 polar or nonpolar?
AlF3 (aluminum fluoride) is a polar molecule due to the difference in electronegativity between aluminum and fluorine atoms. The polar covalent bonds in AlF3 result in an uneven distribution of electrons, leading to a net dipole moment.
Who invented thermite?
Thermite was invented by German chemist Hans Goldschmidt in 1893. He discovered the reaction between aluminum powder and metal oxides to produce intense heat.
