Class 10 chemistry question - why was the periodic table made. Give brief points.
Answers
Period table was formed to give classification of elements into a tabular shape. It was necessary as there are more than 118 elements found on earth and the discoveries still continue.
Thus studying properties of all the elements separately could not be possible and hence grouping them ease the study as many elements have similar chemical or physical properties.
By doing classification we can group similar elements altogether.
Hope this helps you.
If yes mark it as brainliest
1) As different elements were discovered scientists gathered more and more information about the properties of this elements.
2)They found it difficult to organise all that was known about the elements.
3)They started looking for some pattern in their properties, on the basis of which they could study such a large number of elements with ease. This lead to the discovery of periodic table.
