There are a lot of techniques you can use to memorize the periodic table. One of the most obvious ways is through repetition. You repeat the names of the elements over and over again. It is better if you repeat them by reciting them out loud. And to make it easier you can try to memorize them in a small group of five or ten elements at a time. This is like the oldest technique of memorizing but it can be a little bit slow if you’re using this technique.
The second technique is using flashcards. You can make your own flashcards of chemical elements and carry them to learn everywhere. The flashcards are useful to use as a guide. If you forget, you can take a look and continue memorizing.
You can also use acrostics to memorize. This is probably the most popular among students. To use this technique, you can make a sentence out of a group of elements. Your teacher may even make some funny acrostic for you to use.
You can also sing it out loud. A song will make the repetition and memorization process less boring. You may remember the first time you learn the alphabet and you can memorize them easier using the ABC song. It’s the same thing with the periodic table.
There is a quite clear difference between atomic number and atomic mass. On the periodic table, the atomic number can be found on the top left corner. It shows the number of protons of an atom. The atomic mass can be found in the top right corner. It shows the atomic mass of an atom or the weight of an atom. The atomic mass is a sum of protons and electrons of an atom. So, if you are looking for the electron of an atom, you can simply subtract the atomic mass by the atomic number. The number of atomic masses is usually in decimal and it is increasing in accordance with the atomic number.
The chemical elements on the periodic table are arranged based on the atomic number. It is also based on the periods and groups of elements. The horizontal row shows the periods of the elements and the horizontal row shows the groups. The groups are arranged by chemical properties. The elements with similar properties are gathered in one group.
