Metals and non-metals are the two broadest categories of elements on the periodic table. They differ from each other in their physical and chemical properties. The differences between these two groups are so distinct that it is easy to identify them based on their properties alone.
Metals And Nonmetals Notes
1 METALS AND NON-METALS
The elements fall into two groups: metals and non-metals. Metals tend to be good conductors of heat, electricity, and sound. Metals are also malleable and ductile. These qualities make them useful for many things in our daily lives, like electrical wiring or jewelry.
Non-metals tend to be poor conductors of heat and electricity as well as being brittle (substances that break easily). They’re generally not very useful in our daily lives because they don’t have the properties we need out of a material; however, if you try hard enough, there are some non-metal elements that are used in industry today!
2 Metals and non-metals differ from each other in their physical and chemical properties.
Metals and non-metals differ from each other in their physical and chemical properties. They are basically defined by their ability to conduct heat and electricity. Metals are shiny, malleable, ductile and good conductors of heat and electricity. Non-metals are dull, brittle, non-malleable, poor conductors of heat (except graphite) and electricity.
3 Activity 1 (Physical properties)
- Physical properties of metals and non-metals:
The physical properties of metals and nonmetals are important when understanding the physical properties of elements. The differences between these two types of elements are their melting points, boiling points, density and hardness (that is, how easily they can be scratched).
4 Physical properties of metals and non-metals
Metals are good conductors of heat and electricity
Metals are good thermal and electrical conductors, while non-metals are poor thermal and electrical conductors.
5 Preparation of the sample of metals and non-metals for performing various activities
Preparation of the sample of metals and non-metals for performing various activities
Metals and non-metals are prepared by mixing solutions.
Metal: Copper sulfate solution is diluted with water to make it less acidic, then sodium chloride (table salt) is added to the metal solution, which causes a reaction that produces bubbles. The gas bubbles indicate that there is hydrogen gas in the mixture, which can be used to create electricity.

6 Activity 2 (Chemical properties)
Materials that are poor conductors of heat and electricity are called nonmetals.
Metals belong to the family of elements known as metals because they have high density and are good conductors of heat, electricity and strong. We do not normally find metals in their pure form in nature; they always occur combined with other elements such as oxygen, hydrogen or chlorine.
Metals can be classified into two groups: basic metals (elements) and transition elements (transition metals).
Some of the most common basic elements are iron, copper, zinc, aluminum, magnesium etc. The transition element includes iron pyrite FeS2 which is also known as fool’s gold because it looks like gold but is much cheaper.
7 Chemical properties of metals and Non-metals
The properties of metals and nonmetals are as follows:
PROPERTIES OF METALS:
- They are strong, malleable and ductile.
- They can be hammered into thin sheets or drawn into wires.
- When heated, they become soft and can be molded easily without breaking down completely; when cooled, they regain their original strength and hardness.
- They conduct heat well because of which they are used to store heat in furnaces and radiators as well as household stoves etc.,
- They conduct electricity better than non-metals because of their free electrons present in their outermost layer which allows electric current flow through them; this property is utilized for wiring houses with copper wire instead of wood or plastic wires which cannot be used for such a purpose
8 Activity 3 (Reactivity series)
- The activity series is a chart of metals listed in order of decreasing reactivity.
- This means that the more reactive a metal is, the more active it is.
The reactivity series is arranged with the most reactive metal at the top and least reactive at the bottom.
9 The activity series is a chart of metals listed in order of decreasing reactivity. The more reactive a metal is, the more active it is. The reactivity series is arranged with the most reactive metal at the top and least reactive metal at the bottom.

Manganese (Mn) can be found in nearly all living organisms, including humans, because it serves a number of functions within our bodies. It helps build proteins and enzymes and contributes to bone formation. Manganese also plays an important role in energy production by aiding in converting glucose into ATP (adenosine triphosphate), which gives your body energy for cellular processes like digestion and growth; this process occurs through glycolysis (breakdown of glucose) or glycogenesis (synthesis).

It is important to know what makes a metal a metal and what makes a non metal a non metal.
Metals are substances that have high thermal and electrical conductivity, as well as being malleable and ductile. Metals also have the characteristic of luster, which means they have a bright, glossy surface. Some examples of metals are gold, silver, copper and aluminum.
Nonmetals on the other hand do not have these same qualities. Nonmetals usually lack in luster but they may sometimes be lustrous like glass or mercury. They do not conduct heat or electricity well at all (some are insulators) but some can still be malleable or ductile such as boron fiberglass (which is used for making fishing rods). Most importantly though there is one main difference between metals and nonmetals: The ability for bonding with hydrogen! In short this means if two atoms bond together with each other it’s considered metallic because it obeys rules associated with metals; whereas if two atoms don’t bond together then it’s considered nonmetallic because it violates those same rules..
It is important to remember that a metal is a substance with a metallic luster, malleability, and high density. Nonmetals are all elements except for carbon, which is classified as both a nonmetal and an organic compound.
