Mnemonics: Reactivity Series
A short Mnemonics are memory devices that improve our memory to remember details especially in the form of lists like the atomic value of elements, the order of adjectives, characteristics, steps, stages, parts, etc. If we have a list of words to remember in the same order, we take out the first letters of each of the words and make a sentence that we can easily remember.
Learners of Class X need to learn a list the Reactivity Series, which is a list of metals arranged in the order of their decreasing activities.
Here is the list of Activity Series: Relative reactivities of metals
Mnemonics For Scoring Better in Examinations
For examinations and tests we may need to commit to our memory some bits of information in any subject. Mnemonics can help us mainly to remember lists of words and order of things.

How do we use Mnemonics?
If we have a list of words to remember in the same order, we take out the first letters of each of the words and make a sentence that we can easily remember.
For Example, learners of Class X need to learn a list the Reactivity Series, which is a list of metals arranged in the order of their decreasing activities.
We can use mnemonics for this purpose.
Reactivity Series
Learners need to remember this list of metals in the same order. The Mnemonic trick that we can use here is to take the first letter of each word and create a sentence that they can commit to memory easily.
The first letters are: P S C M A Z I L H C M S G
Mnemonic sentences are easy to remember if they are woven around a specific theme, if they are unique and unusual and if they bring a picture in front of the mind's eye.
One example sentence here could be:
Princess Sophia calculates maths adding zeroes in LCM HCF covering mainly silver and gold.
If learners are able to remember this sentence and associate the P of princess with the P of Potassium and S of Sophia with the S of Sodium and so on they can easily recall this list in the same order.
The sentences need not be meaningful. It can be funny or unique. We should be able to form a picture in our mind when we read the sentence. Here we can imagine a princess named Sophia struggling with maths and and adding zeros to LCM and HCF because she is not able to do the calculation and since she is a princess all her things are in silver and gold and she is covering the LCM and HCF with silver and gold.
