Yoz All O Level takers,
Hope things are going fine on your side.
First of all, i would like to thank Always Lovely for inviting me to share my thoughts and experiences in the World of wonderful Chemistry, and allowing me to give-back to the academia.
Recently, i have questions asking how to memorise the Metal Reactivity Series – in order to answer numerous questions that require the knowledge of the series. I certainly believed that school teachers would have improvised their own ways of helping you to memorize the series. Some are easy while unfortunately others are tough in way (for some that don’t feel connected).
My suggestion is to come up with your own “Songs” or “Riddles” in order to easily memorise it. If you have no clue on how to do it, and do not like the one given by your teachers, perharps you want to try this one out:
Potassium -> Please
Sodium -> Send
Calcium -> Charlie
Magnesium -> Monkey
Aluminium -> And
Zinc -> Zebras
Iron -> In
Lead -> Large
Copper -> Cages
Mercury -> Most
Silver -> Securely
Gold -> Guarded
Hope you will find it useful.
All the Best
Sean
Chemistry Made Easy
First of all, thanks immensely for the wonderful chemistry knowledge that you disseminate.
Mine is a question which i came across in a book and felt challenged because it sounded easy yet I had no answer. Here it is: Given two powdery substances (an element and a compound), how would you categorise each either as an element or a compound?
