How to learn chemical elements

You’ll need a
  • Mendeleev Table.

As part of the curriculum, you will not be required to remember all chemical elements. You’ll only need to learn two or three dozen, which is much easier. It is possible to remember chemical elements by period. Look at the Mendeleev Table. In the first period there are only 2 elements: hydrogen and helium. It won’t be difficult to remember them. In the second period there are 8 elements: lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon. 8 names are not so easy to remember. So resort to associations. What term will immediately be remembered when the word “lithium”? Of course, lithium batteries are batteries in cell phones, laptops, digital cameras, video cameras.


The word “beryllium” is less well known. You may have heard about beryllium bronze (an alloy with exceptional elasticity). If you’re interested in minerals, you’ve probably heard of beryl, some varieties of which (such as emerald, aquamarine) belong to the gemstone category. Well, Conan Doyle’s lovers of creativity can remember his short story “Beryl Diadem.”


How to remember the word “boron”? Boric acid will almost certainly be found in every home medicine cabinet. Remember the great physicist Niels Bohr, the Nobel laureate. And so on. “Carbon” is perfectly associated with the word “coal”, and that the main components of air are nitrogen and oxygen, you know since junior high. Pro fluoride keeps advertising, calling to use toothpaste with this component. And about inert gas neon and there is nothing to say: multicolored neon signs are found everywhere. Similarly, gradually memorize elements in the third and subsequent periods.


You can remember not by period, but by group. Start with the first main group: hydrogen, lithium, sodium, potassium, rubidium, caesium. The last element of the group, the francius, is very little common. Remember that it has the most strongly expressed metal properties. After that, you can learn 4 halogen elements from the seventh main group: fluorine — chlorine — bromine — iodine. Try to remember that bromine is the only non-metall in the liquid state and iodine is in the solid state. The fifth element of the group, the astat, like the francium, is very little common. It is worth knowing that it is the only halogen that exhibits the properties of both non-metal and metal. And gradually in the same way continue to teach elements found in other groups.
