    1.) Is it possible for the number of neutrons and the number of protons
    to be equal?

    2.) Is it possible for the mass number(nucleon number) and atomic number(proton number) of an atom to be equal?

    3.) Is there any energy invovled in the formation of mixture?

    4.) does Mixture has properties that are entirely different from those of its
    individual components?

    can anybody help ?

    Hi there topsyturvy and welcome to PF,
    Yes, infact many of the elements have equal numbers of protons and neutrons. HINT: Look for elements with even nucelon numbers.
    Yes, look at hydrogen
    Yes, think intermolecular forces (potential energy)
    Depends, I'm not sure what you mean, perhaps you could give an example.

    P.s. These look like homework questions to me. If this is the case could you please post them in the homework section in future, thank you.
