18 Elements & Atomic Values
Mnemonic help is suggested for remembering the first 18 elements along with their atomic values. If learners memorise a sentence and then try to link the first H with Hydrogen, the second H with Helium, Lithium with the L of light etc. they can easily remember the order.
Composition of Atoms of the First Eighteen Elements with Electron Distribution in Various Shells
If Class X learners need to learn the first 18 elements and their atomic values they can use Mnemonic tricks.
Composition of Atoms of the first 18 Elements
If we take the first letters we will get H for Hydrogen, H for Helium and so on. Taking all these letters we can try to create a sentence for ourselves.
Here is a sample sentence:
Have her light brown blue candles at night Over flashy neon streetlight, make all sleep peacefully, soon children awake
If learners memorise this sentence and then try to link the first H with Hydrogen, the second H with Helium, Lithium with the L of light etc. they can easily remember the order. The atomic numbers 1 to 18 can be easily remembered. Since the number of protons and electrons remain the same, they only have to learn a few calculations to learn the whole table.
Make your own sentences that are funny, unique, unusual or create a crazy picture in your mind. The crazier it is the better you will remmeber it for a longer period.
Chemistry Exam Preparation
In Chemistry learners have to commit to memory lot of detailed information to get a good percentage in the Class X Board Examination. Just a few samples are covered here. As we get more specific requests from teachers, parents and learners we will add more.
Physics Exam Preparation
Preparing for physics exams requires consistent effort, dedication, and a systematic approach. By understanding the syllabus, mastering the fundamentals, creating a study plan, practicing with previous year question papers, and utilizing reliable resources, you can build a strong foundation in physics. Engage in practical work, seek clarification, and form study groups to enhance your learning experience.
Whenever learners have to study details such as these, they feel they know it but at the time of examination they get confused as to where the image will be formed for which position of object. If they learn these details in comparison and get an overview they will remember it for a longer time. They will be able to draw the ray diagrams based on the table info they have learnt. The information would have registered in their brain with a deeper impression and hence they will be able to remember it for a longer time.
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.
