Answer the following questions below.

1. Metallic materials can be made into wires, food containers, utensils, coins, rods and other useful materials. What properties apply to metals? Which property is illustrated by the rusting of some metals?

2. What property is exhibited by a paper catching fire? How about a metal reacting to acid? Why are they considered as chemical properties?

3. Have you ever tried camping? Note how the materials that you are bringing along in your outdoor adventure is different from the materials that you use at home. Why is that so? Does the properties of these materials has something to do with it?​

Answer:

1.Properties of Metals

An element is a substance made up of one kind of atom; it cannot be separated into simpler parts. For example, the element helium (think hot-air balloons) is made up exclusively of helium atoms.

Elements are generally classified as metals or nonmetals (although some elements have characteristics of both; these are called metalloids).

Three properties of metals are:

Luster: Metals are shiny when cut, scratched, or polished.

Malleability: Metals are strong but malleable, which means that they can be easily bent or shaped. For centuries, smiths have been able to shape metal objects by heating metal and pounding it with a hammer. If they tried this with nonmetals, the material would shatter! Most metals are also ductile, which means they can be drawn out to make wire.

Conductivity: Metals are excellent conductors of electricity and heat. Because they are also ductile, they are ideal for electrical wiring. (You can test this using some household items.

2. A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter observed. Other physical properties, such as the melting temperature of iron or the freezing temperature of water, can only be observed as matter undergoes a physical change.
