No, Hydrogen makes up approximately 75% of the universe's elemental matter
No. In the universe (in general) the heavier the element, the less it is available. This is different than what is in our planet though. In the earth's crust, the most common elements are oxygen, silicon, and aluminum. Though they are not necessarily the most available due to the difficulty in extracting these and their level of dispersion.
Some elements were not predicted because they were unstable and quickly decayed into other elements, making them difficult to observe or study. Additionally, some elements exist in very small quantities or under extreme conditions that were not present when the periodic table was initially created.
The most common elements for a compound are the following:HydrogenOxygenCarbonNitrogenChlorineIodinePotassiumBromineCesiumFluorineRubidiumWhy you might ask?These are all the natural occurring Alkali Metals, Halogens, and Diatomics. Carbon and Hydrogen are needed for basic sugars, hydrocarbons, carbohydrates, and much more so I threw them in there.
Yes, The elements hydrogen, nitrogen, oxygen, and sulfur are all molecular elements that exist in nature. Due to their reactivity, it is rare to find the halogens and phosphorus in their elemental forms in nature.
These elements exist as compounds.
The millions of compounds that exist are made from approximately 115 elements!

The elements having atomic number higher than 92 do not exist naturally in large quantities they are either in traces or as short life synthetic elements so their most of the properties including hardness can not be determine practically.
Fundamental quantities are independent of other physical quantities, while derived quantities are based on combinations of fundamental quantities using mathematical operations. Derived quantities cannot exist without fundamental quantities as they rely on them for their definition and calculation.
If no elements existed, nothing would exist.

Most elements exist in the state of matter known as solids at room temperature and pressure. Some elements can also exist as liquids or gases depending on the conditions.
Anywhere where negative quantities exist.
No, for all elements the smallest particle that can exist independently is an atom.
94 natural elements and 14 artificial elements
