The Periodic Table only displays elements. The symbols for the elements are emphasised because that is the most important item of information in the table. Other information, such as atomic weight, etc., are given less emphasis.
All of the substances found in the Periodic Table are considered as elements. None others are.
As of 2009, there are 118 elements on the periodic table. Of those, 92 occur in nature. The others are artificially created.
Periodic trends illustrate how some elements are very reactive while others are stable.
The modern periodic table was derived based on the periodic law, which states that the properties of elements are a periodic function of their atomic number. Dmitri Mendeleev and Lothar Meyer independently developed versions of the periodic table by arranging elements in order of increasing atomic number and grouping elements with similar properties together. Mendeleev's table also left gaps for undiscovered elements, allowing for the prediction of properties of these elements.
All of the others in the same row of the Periodic Table as sodium.
Ununoctium was discovered (prepared) in 2006; old Mendeleev tables (printed before 2006) don't contain ununoctium.
Periods and series are used when grouping elements. Elements are listed in rows, as periods, on the periodic table so that each is grouped with others with similar properties.
Take a look at a periodic table. All elements after Uranium were discovered fairly recently, within the last 100 years or so. Some others, such as Technetium and Francium, were also discovered in that time.Take a look at a periodic table.

The artificially made elements on the Periodic Table are all radioactive substances, such as technetium and curium, which have important applications in the fields of nuclear medicine, space travel, and nuclear energy research, among others.
The periodic table does. If you mean the actual elements, nothing in the universe can contain all elements at once, since many are to unstable to be formed and exist while the others are being created.
The periodic table was created to organize the elements based on their atomic structure and properties. It helps scientists understand the relationships between different elements and predict their behavior. The table's layout also allows for patterns and trends to be easily identified.
