What is an element, compound and mixture?
An element consists of atoms sharing an identical number of protons in their atomic nuclei. It represents the fundamental and indivisible form of matter, incapable of undergoing further simplification via ordinary chemical means.
A compound, conversely, forms when two or more distinct elements chemically unite in precise proportions, forming a distinct substance with its unique properties.
A mixture, on the other hand, encompasses a blend of two or more substances physically intermingled without undergoing chemical bonding.
