Why do we have a periodic table?
“If you memorize the periodic table it will speed you up if you’re a chemist, but by and large, the reason you have a periodic table is so that you can store that information outside of your body. That way it frees up some part of your brain to do something else.”.
Is a non-metal a solid?
So, non-metals are brittle instead of solid. And they are not ductile (you cannot make them into thin wires) or malleable (they can not be made into thin sheets. And, instead of easily losing electrons as metals do, non-metals gain them through chemical reactions. Apart from this, some non-metals are liquid.

The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on ...
What are metals and nonmetals?
In chronological order, this section discusses metals and nonmetals (and metalloids); categories of elements; groups and periods; and periodic table blocks. While the recognition of metals as solid, fusible and generally malleable substances dates from antiquity, Antoine Lavoisier may have the first to formally distinguish between metals and nonmetals ('non-métalliques') in 1789 with the publication of his 'revolutionary' Elementary Treatise on Chemistry. In 1811, Berzelius referred to nonmetallic elements as metalloids, in reference to their ability to form oxyanions. In 1825, in a revised German edition of his Textbook of Chemistry, he subdivided the metalloids into three classes. These were: constantly gaseous 'gazolyta' (hydrogen, nitrogen, oxygen); real metalloids (sulfur, phosphorus, carbon, boron, silicon); and salt-forming 'halogenia' (fluorine, chlorine, bromine, iodine). Only recently, since the mid-20th century, has the term metalloid been widely used to refer to elements with intermediate or borderline properties between metals and nonmetals. Mendeleev published his periodic table in 1869, along with references to groups of families of elements, and rows or periods of his periodic table. At the same time, Hinrichs wrote that simple lines could be drawn on a periodic table in order to delimit properties of interest, such as elements having metallic lustre (in contrast to those not having such lustre). Charles Janet, in 1928, appears to have been the first to refer to the periodic table's blocks.
What is the atomic number plotted against?
Atomic number plotted against atomic radius, excluding the noble gases. Atomic radii vary in a predictable and explainable manner across the periodic table. For instance, the radii generally decrease along each period of the table, from the alkali metals to the noble gases; and increase down each group.
