Answer:
Taking into account the concepts presented in chemistry with respect to elements and compounds, it is possible to affirm that the compounds are formed by two or more elements.
Explanation:
Two or more chemical elements have the ability to bind -by forming bonds- to obtain a compound. This occurs randomly in nature.
The bonds between the elements that form a compound must be stable enough to ensure the stability of the molecule. A chemical compound can only be separated into the elements that form it by chemical processes.
The bonds types that form compounds can be:
- <em>Ionic bond.</em>
- <em>Covalent bond.</em>
- <em>Coordinated covalent bond.</em>
- <em>Metallic bond.</em>
It is necessary to mention that chemical elements are called atoms, and the bonds between them are molecules. The physical and chemical properties of a compound will be different from the properties of the elements that form it.
