BSL Chemistry Glossary - periodic table - definition

Translation: You can see the Periodic Table below. There are rows of elements - over a hundred of them. The elements are organised in columns, and the ones in each column have similar properties. So if you know about one element in the column, you will know that the other ones above and below it are similar. The left and middle of the table is made up of metals. On the right the elements are non-metals.
