Question

Explain how modern science has benefited from the invention of the Periodic Table of the Elements.

written in 250 words minimum

Answer 1

1. The periodic table organizes elements according to similar properties so you can tell the characteristics of an element just by looking at its position on the table.

2. The table can be used to predict properties of elements yet to be discovered, although these new elements are all highly radioactive and break down into more familiar elements almost instantly.

3. The table is useful for modern students and scientists becuase it helps predict the types of chemical reactions that are likely for an element.

Rather than memorize facts and figures for each element, a quick glance at the table reveals a lot about the reactivity of an element, whether it is likely to conduct electricity, whether it is hard or soft, and many other characteristics.

4. Another useful feature of the table is that table provide all the information you need to balance chemical reactions at a glance.

5. The table tells element's atomic number and usually its atomic weight. The usual charge on an element is indicated by an element's group.

6. Elements in the same column as each other share similar properties.

7. Elements in the same row as each other share highest unexcited electron energy level.
