1) Atoms are the building blocks of all matter and are made up of protons, neutrons, and electrons.
2) Elements are substances made of only one type of atom, while compounds contain different types of atoms bonded together.
3) Some common elements and their symbols include hydrogen (H), helium (He), carbon (C), oxygen (O), sodium (Na), iron (Fe), copper (Cu), and silver (Ag).
all the information you need about metals , nonmetals their ores at brief .
dont get scared by no. of slides it will be over within no time.
sorry ,the number pictures are less

Chapter 3.metals and non metals priya jhaPriya Jha
An element is the simplest form of matter that cannot be split into simpler substances or built from simpler substances by any ordinary chemical or physical method. There are 118 elements known to us, out of which 92 are naturally occurring, while the rest have been prepared artificially. Elements are further classified into metals, non-metals, and metalloids based on their properties, which are correlated with their placement in the periodic table.Metals
With the exception of hydrogen, all elements that form positive ions by losing electrons during chemical reactions are called metals. Thus metals are electropositive elements with relatively low ionization energies. They are characterized by bright luster, hardness, ability to resonate sound and are excellent conductors of heat and electricity. Metals are solids under normal conditions except for Mercury.Nonmetals
Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements with high ionization energies. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gases, liquids or solids.Metalloids
Metalloids have properties intermediate between the metals and nonmetals. Metalloids are useful in the semiconductor industry. Metalloids are all solid at room temperature. They can form alloys with other metals. Some metalloids, such as silicon and germanium, can act as electrical conductors under the right conditions, thus they are called semiconductors. Silicon for example appears lustrous, but is not malleable nor ductile (it is brittle - a characteristic of some nonmetals). It is a much poorer conductor of heat and electricity than the metals. The physical properties of metalloids tend to be metallic, but their chemical properties tend to be non-metallic. The oxidation number of an element in this group can range from +5 to -2, depending on the group in which it is located.
all about metal and nonmetal of class 10 from physical to chemical....

made by student of 10th class only ..
short and sweet slides for quick revision...
HOPE IT MAY HELP U ...☺☻☺☻☺☻
This presentation describes lots about the metals and non-metals. It also talks about the periodic tabe, physical and chemical properties of metals and non-metals and usses of them. Go ahead and learn beyond the Earth's crust as scientists still continue to dicover new things around the earth. After going through this presentation you will have complete understanding about the metals and non-metals.
Enjoy!!
To know a range of metals that have specific uses. Metals are found in the Earth, sometimes as elements and sometimes in an ore.
What is a metal ore?
This is the concentration of metals or minerals (solid elements or compounds) which occurs naturally in the Earth’s crust.
A mineral which contains a reasonably high percentage of a metal for economic extraction is called a metal ore.

Unit 2, Lesson 2.6 - Elements and Compounds
Lesson Outline:
1. Matter: An Overview
2. Pure Substance
3. Element vs. Compound
4. Metals, Metalloids, Nonmetals
5. Law of Definite Composition
Electrochemistry is the study of electricity and how it relates to chemical reactions. In electrochemistry, electricity can be generated by movements of electrons from one element to another in a reaction known as redox or oxidation-reduction reaction.

Atoms
Atoms are the “building blocks” of all matter and are the
simplest form of molecule. They are all made up of
protons, neutrons and electrons. They look something like
this:
The Nucleus – this
contains neutrons and
protons
Electrons – these orbit
around the nucleus
3. 08/11/12
Elements
If a solid, liquid or gas is made up of only one type of
atom we say it is an element. For example, consider a
tripod made up of iron:
These atoms are
ALL iron – there’s
nothing else in here
4. 08/11/12
Compounds
Compounds are
different to
elements. They
contain different
atoms. Here are
some examples: Methane
Sodium
chloride (salt)
Glucose
