Why was mendeleev's table so useful?

Answer 1

Because it organized all of the existing elements and helped scientist discover more elements.

Answer 2

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

• It memorizes 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.

• Elements in the same column as each other (groups) share similar properties. For example, the elements in the first column (the alkali metals) are all metals that usually carry a 1+ charge in reactions, react vigorously with water, and combine readily with nonmetals.

• Elements in the same row as each other (periods) share highest unexcited electron energy level.

• Another useful feature of the Periodic Table is that most table provide all the information you need to balance chemical reactions at a glance. The table tells an elements atomic number and usually its atomic weight. The usual charge on an element is indicated by an element's group.

Answer 3

Mendeleev's table of elements was so useful because it organized elements by increasing Atomic Mass and grouped elements with similar properties together. This allowed scientists to predict the properties of undiscovered elements and their compounds. It also provided a systematic way to understand the relationships between elements and their chemical behavior.

Answer 4

Mendeleev's table was useful because it indentifies the elements, and classifies them as metals, non metals or metalloids, as well as noble gases.

Answer 5

Because it organized all of the existing elements and helped scientist discover more elements.

Answer 6

It showed the elements arranged by atomic number

Answer 7

One powerful outcome, was with the table, chemists could now look for elements which were yet to be found. For they knew what properties the new element would have.

Answer 8

Once it looked like the periodic table had "missing" elements, the missing elements could be predicted and searched for. Many elements were found this way.

Answer 9

Mendeleev's table comprised of elements having same properties together. It made study of elements easier, however it had certain drawbacks.
