Assuming that "least nonmetallic" means the same as "most metallic", francium.
no, chlorine is not metallic, but it can come in various forms, most commonly a yellowish gas.
The items that contain more than one element and have metallic properties are known as alloys. They can be an intermetallic compound that lacks phase boundaries, a metallic phase mixture, or a solid element solution.
The most metallic element after francium is cesium. Cesium is located in Group 1 of the periodic table and has properties that are characteristic of metals, such as high electrical conductivity and metallic luster.
Cadmium.
Assuming that "least nonmetallic" means the same as "most metallic", francium.
Rubidium (Rb) is an alkali metal.
No, stainless steel is not a nonmetallic element. It is a metallic alloy composed mainly of iron, with a minimum of 10.5% chromium to give it its corrosion-resistant properties.
Limestone is a nonmetallic mineral. It is a sedimentary rock primarily composed of calcium carbonate, which is a chemical compound with a nonmetallic element (calcium) and a nonmetallic element (carbon) bonded together. Metallic minerals, on the other hand, are composed of metals or have metallic properties. Limestone does not fall into this category.
Antimony is a metalloid which means that it has metallic and nonmetallic properties and it is element 51 in the Periodic Table lying in the diagonal metalloids in the p group. The metallic and nonmetallic properties may be, for example, that it is grey and shiny like a metal but it may also be brittle and not conduct heat and electricity like a nonmetal.
iron
It is metal as it conducts electricity and it is on the left side of that big black line in the periodic table. It is in fact used in wires for it's conductive properties.
no, chlorine is not metallic, but it can come in various forms, most commonly a yellowish gas.
An overwhleming amount of steel is iron; it is therefore metallic.
Sulphur is the element which is non metallic and has 32 as its atomic mass. It is placed in group-16 of the periodic table.
A metalloid is an element that has both metallic and nonmetallic properties. When combined they form an alloy. Metalloids are usually semiconductors.
The items that contain more than one element and have metallic properties are known as alloys. They can be an intermetallic compound that lacks phase boundaries, a metallic phase mixture, or a solid element solution.
