How many elements does a compound have
WebApr 22, 2015 · Now there are many more phases than the classic states solid, liquid, gaseous. Just regular ice has eleven phases and magnetic materials might change their magnetic behavior in addition to their stiffness. WebAn atom of an element in a compound will have a positive oxidation state if it has had electrons removed. Similarly, adding electrons results in a negative oxidation state. We have also distinguish between the possible and common oxidation states of every element. For example, silicon has nine possible integer oxidation states from −4 to +4 ...

Any substance consisting of two or more different types of atoms (chemical elements) in a fixed stoichiometric proportion can be termed a chemical compound; the concept is most readily understood when considering pure chemical substances. It follows from their being composed of fixed proportions of two or more types of atoms that chemical compounds can be converted, via chemical reaction, into compounds or substances each having fewer atoms. A chemical formula i… Webcompounds are molecular or ionic atomic elements those that exist in nature with single atoms as their basic units (most elements) molecular elements these elements exist as diatomic molecules, two aoms of that element bonded together as their basic units. molecular compounds compounds formed from two or more nonmetals Ionic compounds
