Here you can learn about the periodic table which is most important for chemistry subject. In this presentation, you can know about metals, non-metals, group1-17, blocks s,p,d,f and periods in the periodic table.

2. Periodic Table is a tabular arrangement of elements, ordered by their atomic
number, electron configuration and recurring chemical properties.
In periodic table, the arrangement of elements are arranged from left to right and
top to bottom in order of increasing atomic number.
The different rows of elements present in periodic table are known as periods.

3. Group 1 includes all the Alkali Metals and Hydrogen.
Alkali metals are soft metals, but highly reactive metals and reactivity of
these metals increases down the group.
In this group, Hydrogen behaves different from all other metals.
Scientists disagree over whether it should be placed in group 1 or group
17.

4. Group 2 includes all Alkali Earth Metals.
The metals present in group 2 are reactive metals with
different flame colors.
In this group elements have two electrons in their outermost
“S” sub-shell.

5. Group 3 is a family of transition metal elements.
In this group each have a valence electron configuration of d1s2.
These elements are found in the +3 oxidation state.
Scientists are confused whether lanthanum and actinium, should
be included in this group.

6. This group is a group of transition metal elements and
they have high melting points.
In this group, metals have a valence electron configuration
of d2s2.

7. This group is a group of reactive transition metal elements
and they have high melting points.
In this group, metals have a valence electron configuration of
d3s2.

8. It is a group of transition metal elements.
According to Aufbau principle in this group each have a
valence electron configuration of d4s2. But, chromium and
molybdenum are exceptions to this rule and have a valence
electron configuration of d5s1.

9. This group consists transition metal elements,
manganese, technetium, rhenium and bohrium.
In this group, metals have a valence electron
configuration of d5s2 .

10. This group is a group of shiny, silvery transition metal
elements, iron, ruthenium, osmium and hassium.
In this group, metals have a valence electron configuration of
d6s2 .

11. This group is a group of silvery-white transition metal
elements, having high melting points. This group contains
cobalt, rhodium, iridium and meitnerium.
In this group, metals have a valence electron configuration
of d7s2 .

12. It is a group of white to light grey transition metal elements.
This group contains nickel, palladium, platinum and
darmstadtium.
According to Aufbau principle, each have a valence electron
configuration of d8s2

13. It is a group of transition metals and it includes copper, silver and
gold. Sometimes they are called the 'coinage metals'.
In this group, metals have a valence electron configuration of d10s1 .

14. It is a group of metals and have a full d sub-shell.
In this group elements have low melting points and mercury is only
the metal that remains liquid at room temperature.

15. This group is the boron group.
In this group all elements are metals except the boron, Boron is
a metalloid.
Aluminium and Boron have three electrons in their outer
electron shell.

16. This group is known carbon group.
In this group there are combination of non-metals, metal and
metalloids.
Group 14- Carbon and silicon each have four electrons in their
outer electron shell.

17. This group is known as the nitrogen group or pnictogens group.
This group contains a combination of non-metals, metalloids and
metals.
Nitrogen and phosphorus contains five electrons in their outer
electron shell.

18. It is called the chalcogens or oxygen family.
This group contains a combination of non-metals,
metalloids and metals.
Group 16- Oxygen and sulfur have six electrons in their
outer electron shell.

19. This group is known as the halogens.
This group contains highly reactive non-metals.
This group contains the elements, which are three states of matter at
room temperature and pressure.
Bromine is a liquid, Fluorine and chlorine are gases and iodine is a
solid.

20. This group elements are commonly known as the noble gases and they
are typically unreactive.
They are also known as the inert gases
In this group, reactivity increases down the group. Radon being the
most reactive in this group.
In this group noble gases each have a full outer electron shell.

21. A block in the periodic table of elements is the set of adjacent groups.
Each block is named after its characteristics orbital. There are four blocks in a
periodic table. s-block, p-block, d-block and f-block.
The periodic nature of the filling of orbitals, as well as emergence of
the s, p, d and f blocks is more obvious.

22. The block “s” includes the alkali metals and alkaline earth
metals.
These metals are soft and reactive in nature. It also contains
hydrogen and helium which are metals and gases.
In this block elements have their valence electrons in s orbitals.

23. This block contain elements with
quite varied properties.
This block contains metalloids,
metals and non-metals.
P sub shell can hold maximum of six
electrons in three orbitals.

24. Block d is also commonly called as the transition metals.

25. Block f contains lanthanides and actinides.
These metals are soft and also contains radioactive
Metals in f block.
In this block sub-shell can contain up to 14 electrons.
