Let's remember the element symbol with a 4-choice quiz.
Check the learning outcomes with the exam!
Convenient for preparing and reviewing science and chemistry classes!
Feel free to study in your spare time, such as between classes or on the train or bus to school!
First of all, let's remember the element symbol to read and write the compound formula.
[Element symbol quiz]
You will be asked 25 questions for each question.
You can quit at any time you like, so feel free to study.
・ Periodic table of elements ・ ・ ・ (It's difficult, but you can remember the periodic table)
・ Elemental symbol ・ ・ ・ (It's the most basic problem)
・ Atomic number, period, group ...
・ Atomic weight (4 digits) ・ ・ ・ (If you can remember it, it's quite a tsuwamono!)
[Element symbol list mode]
You can see the explanation by tapping the element symbol.
You can also see the position in the Periodic Table of the Elements, the purpose of the element, and the origin of the English name.
* About atomic weight
Internationally recognized atomic weights have been discussed by the International Union of Pure and Applied Chemistry (IUPAC) Atomic Weight and Isotopic Abundance Committee (CIAAW) and approved and published by IUPAC.
The 4-digit atomic weight was originally created by the Atomic Weight Expert Committee of the Chemical Society of Japan based on this published value.
The atomic weight indicated by () is the mass number of only one typical isotope because it is an unstable element.
