Compound
In a compound chemical elements are linked by chemical bonds.
Every chemical compound is unique and different from the ELEMENTS it contains
Color change indicates a chemical reaction has occurred. The mixture of elements has different chemical properties than the original individual elements.
A substance is called a compound when it is made up of two or more different elements chemically bonded together. Compounds have a fixed chemical composition and properties that are different from the elements that make them up.
Now are known 118 chemical elements.
Salts are chemical compounds not elements.
Atoms of different elements unite during chemical changes to produce at least one chemical compound.
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.
Today are known 118 chemical elements.
The chemical behavior of different elements is determined by their electron configurations. Elements with similar electron configurations exhibit similar chemical behavior. For example, elements in the same group of the periodic table tend to have similar chemical properties due to their shared electron configurations.
All the electrons in all chemical elements are identical; only the numb er is different.
Compound
If you mean two different elements, no. That would defeath the purpose of having chemical symbols.
In a compound chemical elements are linked by chemical bonds.
