Question

give two two example molecules of element and of compound​

Answer 1

Answer:

Elements – Elements constitute the simplest chemical substances in which all the atoms are exactly the same.

• An example of an element is Nitrogen atom(N), Nitrogen gas (N2), Nitrogen ion(N3-) and Nitrogen isotopes (Nitrogen-13, Nitrogen-14, and Nitrogen-15).

Compounds – Compounds are chemical substances made up of two or more elements that are chemically bound together in a fixed ratio.

• Example of compounds includes water (H2O), Hydrogen Peroxide (H2O2), etc. You could see water’s chemical formula, it says it has 2 atoms of Hydrogen combined with 1 atom of oxygen and in hydrogen peroxide, it has 2 atoms of hydrogen and two atoms of oxygen.

• Similarly,  an example of salt would be the table salt (NaCl) which has 1 atom of sodium and one atom of chlorine.
