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.
They are molecular compounds. MgCL2 is an iconic compound. Molecular compounds are covalent compounds in which the elements share electrons via covalent bonds.
Explanation: When you chill a substance when it is mixed with another substance, ( chilled vinegar mixed with sodium bicarbonate will react slower for instance) it reacts slower do to the molecules slowing down when chilled.
