How to learn chemical elements

Students who started to study chemistry, are often faced with great difficulty trying to learn the names and symbols of chemical elements. They think that this is an impossible task, because of the more than 100 elements. However, there are many effective techniques that can help.

You will need

• Periodic Table.

Instruction

1. In the curriculum you do not need to memorize all the chemical elements. You will need to learn only two or three dozen, and it is much easier. You can memorize chemical elements by periods. Look at the periodic Table. In the first period only 2 elements, hydrogen and helium. We are to remember them is not difficult. In the second period has 8 elements: lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon. 8 names to remember are not easy. Therefore, resort to the Association. What is the term reminds you of the word "lithium"? Of course, lithium batteries batteries in cell phones, laptops, digital cameras, camcorders.
2. The word "beryllium" is less known. You may have heard about beryllium bronze (an alloy with exceptional elasticity). If you are interested in minerals you may have heard of beryl, some varieties of which (e.g., emerald, aquamarine) belong to the category of precious stones. Well, the fans of Conan Doyle may recall his story "the Beryl circlet".
3. How to remember the word "Bor"? Boric acid almost certainly will be in every home medicine Cabinet. Remember the great physicist Niels Bohr, the Nobel prize winner. And so on. "Carbon" is perfectly synonymous with the word "coal", and that the main components of air are nitrogen and oxygen, you know with the younger classes. About fluoride insists is calling to use toothpaste with this component. And about the inert gas neon, and say nothing: multi-coloured neon signs everywhere. Similarly, gradually memorize the elements in the third and subsequent periods.
4. You can remember not to periods and groups. Start with the first main group: hydrogen, lithium, sodium, potassium, rubidium, cesium. The last element of the group, France, is very little known. Remember that he had most strongly expressed metallic properties. After that, you can learn 4 elements of the halogen from the seventh main groups: fluorine – chlorine – bromine – iodine. Try to remember that bromine is the only nonmetal that are in a liquid, and iodine is a solid. The fifth element of the group, astatine, like France, very few distributed. About it should know that it is the only halogen which exhibits properties as a nonmetal and metal. And gradually likewise continue to teach the elements found in the other groups.
