Over time a color scheme has been added to the periodic chart to help understand which elements belong to named categories. The noble gases have low melting and boiling points. While groups and periods are useful in understanding the chemical families, elements are also seen as being organized by blocks. Groups are the horizontal rows and represent families of elements.

So in order to finish it quickly he constructed a table of all the elements according to their atomic weights to understand the elements better and to complete his work easily. Dmitry Mendeleev was supposedly late in submitting his work on 63 elements. Mercury and bromine are only two elements that are liquid in room temperature. The colors on the table correspond to the different families of elements such as alkali metals, transition metals, lanthanides, actinides, metalloids, halogens, and noble gases. Periodic table of Mendeleev is in the ascending as order of atomic weight and the modern periodic table is according to increasing atomic number. 75% of the elements on the periodic table are metals. There are 118 elements in the periodic table today, but only 90 are commonly found in nature, the other elements are synthetically made. FREE PRINTABLE PERIODIC TABLE OF ELEMENTS WORKSHEETS UPDATE
Its basic uses are to locate bone cancers in x-rays. The latest update was made just in December 2018.
The first man-made element is Technetium. The Noble Gases Helium, neon, argon, krypton, xenon, and radon are unreactive. The atomic weight of Uranium is 238 being the heaviest element. 
The lightest element is Hydrogen its atomic weight is 1 and that is why it is found in the top left corner of the periodic table.The only metal which is so soft that it can be to cut with a knife and light enough to float on water is Lithium.The International Union of Pure Applied Chemistry (IUPAC) is takes care of the periodic table.90 elements are found in nature, and others are man-made. There are a total of 118 elements in the periodic table.It is called the periodic table because the rows are called periods.
