The top number on elements in the periodic table is the atomic number, so when you look at the periodic table you can see that 42 is Mo (Molybdenum), and this is the only element with that atomic number.
Hope this helped! Please rate 5 starts and hit thanks if it did :)
Answer:
The prime difference lies in the fact that pure substances cannot be physically separated while mixtures can be. The separation of a mixture into its different parts is done by using physical techniques like distillation, filtering and particle separation.
The estimated number of compounds
formed by the elements in the periodic table is far greater than 118 because
elements can combine in various ways. Compounds are substance composed of more
than one element held together by chemical bonds. Additionally, they can be
converted to a different chemical composition by interaction with another
compound via a chemical reaction.
