Answer is Wrong!
Answer is Right!
The answer is A. Mercury.
Mercury is a liquid metal, while the other options are all solid metals. Mercury is also the only metal that is liquid at room temperature.
- Mercury is a chemical element with the symbol Hg and atomic number 80. It is a silvery-white, heavy, and toxic liquid metal. Mercury is a member of the group 12 elements in the periodic table and is one of the five elements that are liquid at standard temperature and pressure. Mercury is also the only metal that is liquid at room temperature.
- Bromine is a chemical element with the symbol Br and atomic number 35. It is the third member of the halogen group and is a highly reactive, corrosive, and flammable pale red-brown liquid at standard temperature and pressure. Bromine is the only non-metallic element that is liquid at standard temperature and pressure.
- Aluminium is a chemical element with the symbol Al and atomic number 13. It is a silvery-white, lightweight, and ductile metal. Aluminium is the most abundant metal in the Earth’s crust, and the third most abundant element, after oxygen and silicon. Aluminium is a member of the group 13 elements in the periodic table and is the second most abundant element in the Earth’s crust, after oxygen.
- Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is a member of the group 1 elements in the periodic table and is the sixth most abundant element in the Earth’s crust. Sodium is a highly reactive metal that is used in a variety of applications, including the production of sodium hydroxide, sodium carbonate, and sodium chloride.
- Titanium is a chemical element with the symbol Ti and atomic number 22. It is a lustrous, silvery-white transition metal that is highly resistant to corrosion. Titanium is a member of the group 4 elements in the periodic table and is the ninth most abundant element in the Earth’s crust. Titanium is a strong, lightweight metal that is used in a variety of applications, including the aerospace industry, the automotive industry, and the medical industry.
