The answer is D. Aluminum.
Iron, nickel, and cobalt are all ferromagnetic metals, meaning they are attracted to magnets. Aluminum is not ferromagnetic.
Iron is a chemical element with the symbol Fe and atomic number 26. It is a metal in the first transition series and is the most common element (by mass) on Earth. It is a member of the iron group in the periodic table: a group of elements in the periodic table of the chemical elements that have a similar chemical behaviour. The atomic number of iron is 26, and it has a relative atomic mass of 55.845. Iron is a silvery-white metal that is found in the Earth’s crust in the form of iron ore. It is a very strong metal that is used in many different applications, including construction, machinery, and transportation.
Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white metal that is found in the Earth’s crust in the form of nickel ore. It is a very strong metal that is used in many different applications, including coins, batteries, and jewelry.
Cobalt is a chemical element with the symbol Co and atomic number 27. It is a silvery-white metal that is found in the Earth’s crust in the form of cobalt ore. It is a very strong metal that is used in many different applications, including magnets, batteries, and jewelry.
Aluminum is a chemical element with the symbol Al and atomic number 13. It is a silvery-white metal that is found in the Earth’s crust in the form of aluminum ore. It is a very strong metal that is used in many different applications, including construction, machinery, and transportation. However, aluminum is not ferromagnetic. This means that it is not attracted to magnets.
