<em>Answer:</em>
- Element: Element are pure substance consist of same type of atoms
- Compound: Form by combination of atoms of different elements.
<em>Distinguish features:</em>
- Compounds represented by chemical formula while elements are represented by symbols.
- Compounds have fixed ratios of atoms of different elements while in elements are distinguished by atomic no.
- Compounds can be converted into simple substance by chemical methods but the elements cant be converted into simpler substance by means of chemical methods.
<em>Example:</em>
- Water (H2O) is a compounds.
- Iron (Fe) is an element.
<em>Summary:</em>
- When two or more elements are mixed then compounds are formed.
Answer:
Element.
