All metals are in a solid state except for mercury

The answer is: liquid

All metals exist in a solid state, except for one element: mercury. Mercury is a metallic element that exists in the liquid state, as shown in the periodic table on the left side. The alkali metals, which are all found in the first column of the periodic table, are a subset of metals, distinguished by their luster and reactivity with other elements. In addition to the solid state, metals can also be found in other forms such as alloys and compounds.

All metals are in a solid state, except for one element: mercury. Mercury is a metallic element and has a unique state in that it exists in a liquid state. This is due to its location in the periodic table on the left side. Alkali metals are also found in this area and are distinguished by their luster. In some Arab countries, minerals are known as metals, while chemists call them minerals, which are elements. Chemistry is known as the science that studies all chemical elements, which is why mercury is considered a metal.
