Compounds
All the properties are different for chemical elements and chemical compounds.
The physical properties of a compound may be entirely different from the physical properties of the elements from which the compound is made.
The chemical and physical properties of a compound are different than those of the elements from which it is formed.
When elements combine, the resulting compound is usually very different to the original elements. Take common salt for example. Sodium and chlorine are very reactive elements that you certainly would not allow anywhere near your food, yet sodium chloride is an essential part of our diets.
In general they don't. Table salt (NaCl), which is a solid and one that (within reasonable limits) we can consume safely, is made from a highly reactive metal (Na) and a seriously corrosive gas (Cl).
Compound
It is normal; each compound has specific properties.
A compound has a definite composition, while a mixture's composition can vary.
Salt water is a homogeneous mixture. Salt, however, is a compound. It has its own properties different from the original elements that created it. It was chemically combined and can only be separated by those means.
When element chemically combine, they form compounds that have properties that are similar to those of the uncombined elements
No, compounds do not necessarily have similar properties to their uncompounded elements. Example: Hydrogen and Oxygen are both gasses at normal temperature and pressure, but their compound, dihydrogen oxide (water) is a very distinctly different substance.
