For a particular sample of copper, two peaks were obtained in the mass spectrum,showing an abundance of 69.10% at m/e 63 and 30.90% at m/e 65.

(i) Give the formula of the species responsible for the peak at m/e 65.

(ii) State why two peaks, at m/e values of 63 and 65, were obtained in the mass spectrum.

(iii) Calculate the relative atomic mass of this sample of copper to three significant figures, using the data given above.

(iv)Explain, in terms of its bonding and structure, why the melting temperature of sodium chloride is high.
