With the discovery of large number of elements became difficult to study individually the properties of so many elements and their compound so many attempts were made to arrange elements in such a way that similar elements were grouped together and different elements were separated. Periodic classification of elements is the method by which elements are grouped on the basis of their characteristics i.e. we keep the elements that are similar in one group and the rest of the elements in the other group. Some empty spaces were also left in the periodic table so that the elements that will be discovered in the future can be placed without changing the trending periodicity of the elements.
In this video, we will cover:
1. Why to study Periodic table
2. What is the history of Periodic table?
3. History of Periodic Table.
4. Periodic Law given by Mendeleev’s

8. How to place new elements in the periodic table?
9. Electronic Configuration in Periods
10. S Block Elements
11. P- Block Elements
12. D-Block Elements
13. Electronic Configuration along Groups
14. Metals, Non-metals & Metalloids
15. How Metallic character trend changes?
16. What is atomic radius?
17. Define Ionic radius Trend?
18. What are isoelectronic species?
19. Explaining Ionization Enthalpy
20. Comparing 1st,2nd and 3rd ionization enthalpy
21. What is electron gain enthalpy?
22. Electronegativity
23. Physical Properties
24. Chemical Properties
25. Oxidation /Valence States
26. How to find oxidation states?
27. Anomalous properties of second period elements.
28. Periodic Trends & Chemical Reactivity

LIKE MY WORK

[lavinaxavier]

Her teaching is great, in our school they teach like as if we are goin to ISRO the next day 🤣

[ThalaandThalapathyfan]

"Chemistry without exception, is like Body without soul"

~By me 😂😂

[HarshSingh-qckp]

Pressure is inversely proportional to the number of days left for the exam where "kal se padhenge remains constant" 😅😂😂

[Mamtaa]

Chemistry m jitni theories nhi h usse zyda to exceptions h 😂😂 do you agree ??

let us take a minute to appreciate Roshni ma'am's VIDEO EDITOR.

[Mhetre_yrs_]

Madam, you are helping me a lot.I am a girl from a poor family. I am not in a position to study in coaching classes. I can't express in words how much your YouTube platform has helped so many students like me.

🙏Thank you mam🙏

we can also remember like this
cation has the word cat in it
cat has paws
and 'paws' sounds like "paw-si-tive"



sorry agar kisi ko aur confuse kar diya ho toh 😭😭💀💀
