Metals and Non-Metals form a fundamental classification of elements, playing a pivotal role in understanding the diverse world of chemistry. In Class 10, students delve into the distinct characteristics, properties, and reactions that define these two broad categories. Metals, with their conductivity and malleability, stand in stark contrast to the non-metals, which exhibit varying physical and chemical traits. These notes provide a concise exploration of the essential attributes of metals and non-metals, offering a foundational understanding for students to navigate the complexities of chemical interactions and classifications in the realm of science.
Metals and non-metals class 10th presentation. For all those who have been given an assignment just like me to make a ppt, this might help.
Enjoy 10th grade. In this presentation, we unravel the fundamental differences between these two categories of elements. Explore the conductivity of metals and learn how they play a vital role in electrical systems and technology. Delve into the world of non-metals and uncover their diverse applications, from supporting life as essential components of organic compounds to their roles in various industrial processes.
My presentation isn't just about theoretical concepts. We've included engaging visuals, interactive examples, and real-world case studies to make learning about metals and non-metals both enjoyable and insightful.
Everything has been covered in this. With pictures!
in this presentation you will learn about corrosion about it amazing things we dont know and what are the advantages of alloys and other amazing facts.

Unit 8 - Information and Communication Technology (Paper I).pdfThiyagu K
This slides describes the basic concepts of ICT, basics of Email, Emerging Technology and Digital Initiatives in Education. This presentations aligns with the UGC Paper I syllabus.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

PowerPoint Presentation on Metals and Non Metals
1.
2. A metal is a material (an element, compound, or alloy) that is
typically hard, opaque, shiny and has good electrical and
thermal conductivity. Metals are generally malleable-that is, they
can be hammered or pressed permanently out of shape without
breaking or cracking-as well as fusible (able to be fused or
melted) and ductile (able to drawn out into a thin wire). About 91
of 118 element in the periodic table are metals. Some elements
appear in both metallic and non metallic forms. E.g. Gold, Silver,
Iron, Copper etc.
3. Metals are ductile when they are drawn into thin wires. E.g. Gold,
Copper, Silver, Iron etc.
5. Metals have high density because there is little empty space
between the atoms. Atoms are packed close together in a metal.
E.g. Gold, Copper, Iron etc.
6. Metal are generally known as good conductor of heat and
electricity in which they allows heat and electricity to pass
through it easily. E.g. Gold, Copper, Silver, Iron etc.
7. Metals are sonorous because when we hit any metal object then it
makes the sound. This is known as sonorous. E.g. Bells, Strings
of Guitar etc.
8. Metals are generally hard in nature because they are strong and
can withstand heavy loads over them. Due to this property, they
are difficult to cut and can be use in the construction of heavy
machines, building etc.
9. Metals are malleable so they can beaten into thin sheets by
hammer. E.g. Iron, Copper, Aluminium, Gold etc.
10. As metals are giant lattice structures, the number of electrostatic
forces to be broken is extremely large, and so metals have high
melting and boiling point. E.g. Iron, Copper, Gold, Aluminium
etc.
11. Reaction of metals with oxygen.
Metals form their oxides when react with oxygen .
Metal oxides are basic in nature.
Example
Reaction of iron metal with oxygen:
4Fe+3022Fe20
When iron reacts with moist air, it forms rust. Rust is iron oxide.
Articles made up of iron, such as grills etc. are get rusted
because of reaction with moist air.
Rust is reddish brown in color and is iron oxide.
Iron oxide is basic in nature. It turns red litmus into blue.
12. 2Mg+O22Mgo
When magnesium is burnt in air, it forms magnesium oxide.
Burning in air means reaction with oxygen.
Magnesium oxide forms magnesium hydroxide with water. Solution
of magnesium oxide turns red litmus paper into blue. This means
magnesium oxide is basic in nature.
13. Generally, metals form respective hydroxides when they react with
water.
Reaction of Sodium metal with
water:
Sodium metal vigorously reacts with water and forms sodium
hydroxide along with lot of heat.
Reaction of Potassium with water:
K+H2OKOH+H2
Potassium metal vigorously reacts with water and forms potassium
hydroxide along with lo of heat.
14. Metals give hydrogen gas when they react with dilute acid.
Reaction of Zinc with dilute acid:
Mg+2HCI=ZnCI2+H2
Zinc gives hydrogen gas along with zinc chloride when it
reacts with hydrochloric acid. Similarly, zinc gives
hydrogen gas along with zinc sulphate when it reacts with
sulphuric acid. This method is used to produce hydrogen
gas in laboratory.
17. The non metals are not ductile because they can not be drawn into
thin wires. They easily break on stretching. E.g. Silicon, Boron
etc.
18. Non metals are not sonorous because they do not produce a typical
sound on hitting. E.g. Bromine, Fluorine etc.
19. As compared to metals, non metals have low density because the
bonding between their molecules are generally weak london or
dispersion forces due to which there are less forces of attraction.
Apart from diamond, there is no specific packing in the non
metal. Due to which the volume is quite high and have low
density. E.g. Hydrogen, Carbon etc.
20. It is true that lower melting points are a result of weaker bonds or
a lack of bonds between atoms. Therefore non metals lack
metallic bonding between atoms therefore have lower melting
and boiling point than metals. E.g. Bromine, Fluorine etc.
21. The shape of a non metal cannot be changed easily as they
tend to be Brittle and will break. Elements that have
properties of both metals and non metals are called
metalloids. They can be shiny or dull and their shape can
easily changed therefore non metals are soft. E.g. Carbon,
Phosphorous.
22. Non Metals are generally bad conductors because they have
not free flowing electrons and do not cause intermolecular
vibrations making them the bad conductor of heat and
electricity. E.g. Iodine, Neon etc.
23. Reaction of Non Metals with oxygen:
Non Metals form their oxides when react with oxygen.
Example
Reaction of Sulphur with oxygen:
When Sulphur is burnt in air, it forms sulphur dioxide.
Solution of Sulphur dioxide turns blue litmus red. Sulphur
Dioxide forms sulphurous acid when dissolved in water.
Thus, sulphur dioxide is Basic in nature.
24. When Carbon is burnt in air, it forms carbon dioxide. You
can observe that when coal (Carbon) is burnt in form of
smoke, which contains Carbon Dioxide.
Carbon Dioxide is Basic in nature. The solution of Carbon
Dioxide in water turns blue litmus paper red.
25. Non Metals generally do not react with water. Rather some
Non Metals which react with air are vigorously stored in
water.
Reaction of Non Metal with Dilute acid
Generally, Non Metals do not react with Dilute acid.
