No element contains more than one element.
An alloy
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.
No, Lead Sulfide (galena) is a brittle crystalline solid with semiconducting properties.
Alloy
Potassium.
They are both metal...the more metallic looking of the two is silver
butter yellow, nuggets, grains, malleable, ductile, metal, solid, metallic and element. hope this helps, these are just a few but there are much more.
Sn (tin), which is a metal, is more metallic than Sb (antimony), which is a metalloid.
the more metallic element will be the one below in group # or the one closer to the left in the period( the more metallic will be the one closer to the bottom left corner) since they have the lowest ionization energy and lower electronegativity
No, an alloy is a mixture of two or metallic elements. The metals are not bonded together as a compound, they are just mixed together evenly. Alloys often have physical properties that make them more useful than metallic elements by themselves. Brass is an alloy, for example, composed of the metallic elements copper and zinc. Bronze is a mixture of copper and tin. Different proportions of the constituent metals can mean different properties, which can be changed according to how it will be used.
metallic character encompasses all the charateristics of metals, such as the melting point, conductivity, electromagnet properties, density etc. electropositivity is a measure of an element's ability to donate electrons, and therefore form positive ions. In general, the gretaer the metallic character of a metal, the more electropositive it is.
The properties of nonmetals also tend to vary more from and element to element than do the properties of the metals
