A Periodic Table is a kind of table where chemical elements arranged in order of atomic number, usually in rows form and how "close" they are to one another.
Map describe the route of exact location, when you're traveling somewhere and you are new with the help of map you can go from one place top another some map have ways of showing different altitudes, and some have the sole purpose of showing state or national boundaries.

Gold was discovered a long time before Mendelejev submitted his ideas in the 'Periodic table of elements'. So this can't have been the earliest discovery. Gold is already known from Egyptian hieroglyphs (2600 BC). In Egypt and especially Nubia were the earliest gold-producing areas. The earliest known map is known as the Turin Papyrus Map and shows the plan of a gold mine in Nubia together with indications of the local geology (cit. from wikipedia).
if you mean different shades of color its a physical map You might call it a topographical map.
There are many different types of map available for use. A few of these are, a political map(shows borders), a physical map(show landforms), and topographical map (shows physical features with contour lines), road map (shows roads), and a climate map(it shows different climates).

On the periodic table of elements, the symbol "H" stands for Hydrogen.
explanatory table of symbols used on a map
A map can be used for many different purposes. To find out how to get somewhere, to look over a paticular state or country, or to show you where things are.
A world map shows where places are on our Earth. Different Maps show different things like landforms and altitude of places Most world map include detailed maps of different continents and countries. For example, the world book world atlas include some quick facts about different countries.

Isobars are not part of the Periodic Table. Isobars connect areas of equal pressure on a weather map. However the term "isobar" (meaning "equal weight") is also used to describe isotopes whose atomic nuclei have similar weight. Isobars are isotopes of two different elements with the same molar mass, or, rather, the same mass numbers. The reason they are placed differently in the periodic table is that chemical properties are determined by the number of protons in the nucleus, and the number of electrons in the outer part of the atom, while mass numbers are determined by the number of (protons plus neutrons). Neutrons play almost no part in chemical reactions; a heavier isotope of any element will undergo exactly the same reactions as a lighter isotope, but just very slightly more sluggishly. One striking example of isobars is Argon-40 (18 protons and 22 neutrons) and Calcium-40 (20 protons and 20 neutrons). Both are the most abundant isotopes of these respective elements, comprising well over 90% of each element as found on the Earth. But argon-40 is a noble gas, roughly 1% of the atmosphere, that refuses to enter into chemical reaction with anything, except under the most extreme conditions. Calcium-40, on the other hand, is a rather brittle and reactive metal that tarnishes rapidly in air, and bubbles away steadily as it reacts with water, producing hydrogen gas in the process. These isobars thoroughly deserve their separate placement in the periodic table.
