The element often mistaken as the end of a pencil is graphite. While many people think that the black tip of a pencil is lead, it is actually made of a mixture of graphite and clay. Graphite is a form of carbon that provides the smooth writing ability, while the clay helps to harden the pencil core. Thus, the misconception arises from the historical term "pencil lead."
The densest chemical element is the metal osmium (Os) - 22,57 g/cm3.
Os is the symbol for Osmium, a transition metal. It is an element.
Oxygen Sulphate (OS) is not in the periodic table because it is not an element. Rather, it is a compound made from two elements: Oxygen, and Sulphur. Oxygen is eighth on the periodic table, and sulphur is located at 16. Vertically, they are next to each other.
Atomic number 76 is Osmium, the densest element. Its atomic mass is 190. Atomic number tells you the number of protons, so 76 protons. Atomic mass tells you the sum of protons and neutrons, so there are 190-76 = 114 neutrons.
Fire is not an element on the periodic table; rather, it is a chemical reaction known as combustion, which typically involves the rapid oxidation of a fuel, producing heat, light, and various gases. The elements commonly associated with fire are carbon, hydrogen, and oxygen, as they are often involved in combustion reactions. In a broader sense, fire can be seen as a manifestation of energy release from chemical reactions rather than a distinct element.
Operating System
I think so, I believe there is an option in one of the control panels if I'm not mistaken.

Yes, there is Pencil, and it's free. There are many versions for it like Mac OS or Mac OS X. Personally, I just got it and it sucks.
