A compound is formed when two or more elements bond together.
A chemical compound is formed.
A compound is a substance formed by the chemical bonding of two or more elements in specific proportions. A molecule is the smallest portion of a compound.
Compounds are formed from elements.
Elements that are formed in cool stars are heavy but not heavier than iron. (Elements that are heavier than iron are formed in a supernova.)
Compounds are formed when elements of matter are chemically combined.
They were formed in supernovae.

a baby is formed when a male and a female have sex toghether.
A compound is the pure substance formed from the chemical combination of two or more different elements in a fixed ratio.
Because in a mixture, there are no bonds formed between the elements, and therefore the proportions of each element are unknown, for the mixture as a whole. A mixture is not a chemical change.
Compounds are formed from elements.
A chemical compound. The combination of two or more elements in definite proportions forms a compound. For instance, hydrogen and oxygen combine in a two to one ratio in order to form water. Similarly, one sodium atom reacts with one chlorine atom to form the ionic compound sodium chloride.
It is said that when sun dies from hydrogen to iron elements are formed and when busted spread in space .the other elements are formed by chemical reaction by these elements
