Answers
Good electrical conductors and heat conductors.
Malleable - can be beaten into thin sheets.Ductile - can be stretched into wire.Possess metallic luster.
Opaque as thin sheet.Solid at room temperature (except Hg).
characteristic of compound
A compound is a substance made up of two or more elements chemically combined in a fixed proportion by mass. A compound is formed as a result of chemical reaction, between the constituent elements.

compounds are defined as substances composed of two or more different elements that are chemically combined. Both salt and water are compounds. Salt is made up of the elements sodium and chloride. You can find these elements and others on the periodic table. Here, they are represented with the symbols Na for sodium and Cl for chloride. When sodium and chloride join together, they create the compound sodium chloride, which is represented by the formula NaCl.
Water is also a compound. Have you ever heard of H2O? That is the chemical formula for water. Water is made up of the elements hydrogen and oxygen, which are shown as H and O on the periodic table. As you may have already learned, every element has its own unique set of physical and chemical properties, which enable us to tell them apart. The same can be said for compounds. When elements join together, they create a compound that has new and different properties than those of the individual elements. In this lesson, we will learn about types of properties that help us identify compounds.
Physical Properties
A physical property is a characteristic that can be observed or measured. There are many types of physical properties that can be used to tell compounds apart. Let's look at some of the more common physical properties of compounds. Color and odor are physical properties. These are both very easy to observe using your sense of sight and smell. For example, the salt we learned about, which is actually the compound sodium chloride, is white and odorless, whereas the chemical compound hydrogen sulfide, which has the formula H2S, is colorless and smells like rotten eggs.
