Give some differences between element and compound
Answers
Elements and compounds are pure chemical substances found in nature. Thedifference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions. Examples of elements include iron, copper, hydrogen and oxygen. Examples of compounds include water (H2O) and salt (Sodium Chloride - NaCl)
Elements are listed according to their atomic number on the Periodic Table. Among the 117 known elements, 94 are naturally occurring like carbon, oxygen, hydrogen etc. 22 are artificially produced having undergone radioactive changes. The reason for this is their instability due to which they undergo radioactive decay over a period of time giving rise to new elements during the process like Uranium, Thorium, Bismuth etc. Elements combine in fixed ratios and give rise to stable compounds due to chemical bonds that facilitate compound formation.
1-Made up of only one kind of atom.
2-Element is represented using a symbol.
3-Eg:-Iron, copper, silver, gold, nickel etc.
Compound-
1-Made up of two or more elements .
2-Compound is represented by the chemical formula.
3-Water (H2O), Sodium chloride (NaCl), Sodium bicarbonate (NaHCO3) etc.
