These elements are called "metalloids" : boron, silicon, germanium, arsenic, antimony, tellurium, and polonium. They form a diagonal line on the periodic table running down and to the right. Some allotropes of other elements display the properties of metalloids.
The actinides (mostly f-block elements) and lanthanides (rare earth elements) display properties of their own periods, although having proton counts within the periods 6 and 7. They are not assigned to sequential groups.
Elements with similar properties are usually located in the same Group (column) on the Periodic Table.
The periodic table is the most important chemistry reference there is. It arranges all the knwn elements in an informative array. Elements are arranged left to right and top to bottom in order of icreasing atomic number.
All the components of a mixture are just physically combined, not chemically combined. So the components display the same properties they displayed when separated..
The transition elements are metals. As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat.

None. The periodic table of elements is a convenient way to display all known elements, song with a few fundamental properties of each. No 'laws' are captured here.

They follow a pattern for valence electrons.
Bilateral Symmetry
Generally speaking, elements differ from each other because they display different properties. These properties range from volatility to radioactivity and are determined by the element's atomic number. This number, displayed on the periodic table, indicates the number of protons found in the nucleus of one atom of the element. No two elements share an atomic number, so this is how elements are chemically differentiated.
