Compound

The video explains that compounds are made of atoms held together by strong chemical bonds in fixed ratios. Water is highlighted as a compound with a consistent composition of two hydrogen atoms for every oxygen atom. It is noted that compounds have different properties from their constituent elements, exemplified by sugar, which does not resemble the hydrogen, carbon, and oxygen atoms it comprises.

In what way do the properties of compounds differ from their constituent elements?

What does sugar reveal about the relationship between its constituent elements?
