Easy Trick to remember reactivity series : Katrina : K (Potassium) Ne : Na (Sodium) Car : Ca (Calcium) Mangi : Mg (Magnesium) Alto : Al (Aluminium) Zen : Zn (Zinc) Ferrari : Fe (Iron) Phir Bhi : Pb (Lead) Hame : H (Hydrogen) Cu : Cu (Copper) Mili : Hg (Mercury) Silver : Au (Silver) Audi : Au (Gold) Easy Trick Guys 😊😊😉😉😉

Saw this teacher out of the blue for the first time.... Brother i am mind blown .... I could never understand the 3rd half of this chapter if i hadn't seen this VEDIO.... Than u sooo much it means alot that good teachers still exists rather than our boring school teachers lectures 🦋
@@vanshjoon8796 uk what people like u can't even speak a shit infront.... Cuz y'all are soooo bored that em spending time online for correcting me is such a pleasure... Do it i will feel better about myself being atleast busy enough for my future self to be free. Hehe 🦋
Ma'am i studied this chapter two times before but didn't understand a bit.. and literally in just one watch my concepts are crystal clear realted to the chapter.. all thanks to u ❤️

My suggestion for reactive series is Kedar= k Nath= Na Ca= Ca Maali= Mg Aaloo= Al Zara= Zn Feeka= Fe Pakata=Pb Hai=H ------------Kyuki------------- Court= Cu H= Hg A= Ag A= Au ------------P ka------------- IF YOU LIKE THIS THEN PLEASE SUPPORT MAM❤
She used to explain every single lines of ncert ......i mean.. she is superb ......i love u mam ....you are the best ... every single Pou is crystal clear...
M ye video teaching k competative exam k liye dekhna chahti hun Lya uske liye bhi helpful rah payegi Please reply kren Ya fr bs school students k liye hi?
Underrated as fuq Your videos just are the best Cannot exaggerate more than this also gonna share this with 4 friends Subscribed to you Thank you so much God bless you Comment mat padho shobhit nirvan ke notes padho zyada time nahi bacha hai
Thank you so much ma'am for this amazing lecture really I think I can never understand this chapter in my own life but your teaching styles is mind blowing I have no words to tell about your talent thank you so much ma'am ❤️❤️❤️❤️❤️❤️ I think that every teacher is not similar to you
