A substance that has properties different from the chemical elements in it is a chemical compound. A chemical compound is built from chemical elements that are chemically bonded together. And the "finished product" will have chemical properties that are unique to that compound, and different from the properties of the substances that make it up.
Elements that are close to each other in the periodic table are more likely to readily form compounds. For example, sodium (Na) and chlorine (Cl) readily form the compound sodium chloride (NaCl) because they are adjacent to each other in the same period.
A covalent compound is most likely formed from nonmetals or elements with similar electronegativities. This is because covalent bonds involve sharing of electrons between atoms to achieve a stable electron configuration.
The most abundant compound in clean and dry air is nitrogen gas, which makes up about 78% of the atmosphere. Oxygen is the second most abundant compound in the atmosphere, comprising about 21%.
Not necessarily anything like those of the elements.
compound
If a binary compound is the only reactant in a chemical reaction, the products are likely to be elements that can be formed from the constituent elements of the binary compound. For example, if the binary compound is AB, the products could be the elements A and B or compounds that can be formed from A and B.
In most cases, when two elements form a compound, the new compound has a set of chemical properties that are entirely different from its reactants. However, in the case of diatomic compounds, such as O2, then yes, the compound retains the properties of its elemental parts.
Table sugar, which most likely is sucrose, is a compound.
Water
carbon
Iron.
Silica is the most abundant compound found in magma. In the earth's crust, oxygen and silicon are the abundant elements which form the compound known as silica.

The compound that makes up most organisms is carbon. Yes, however, carbon is an element not a compound, water is a common compound in all living things.
If you meant "compound" the answer is "H2O" or "water." If you meant "element" the answer is "hydrogen."
Most roads are made of asphalt concrete, which is a mixture of asphalt, which is a chemical compound, with gravel, which is just a bunch of little rocks. Asphalt, being a petroleum product, is probably just a hydrocarbon, meaning that the most common elements would be hydrogen and carbon.Maybe you just want to know a compound or ingredient for roads, in which case the answer is just asphalt. If you actually care about chemical elements, then probably hydrogen is most common.
