<h2>Answer:</h2>

\bold{Cu^+} ions have a "pseudo-noble-gas" electron configuration.

<h2>Explanation:</h2>

The ion with the (n-1) d^{10} electron configuration is known as Nobel gas. The nature of noble gas is that the cations in this electron configuration are stable.

<u>The Pseudo-noble gas has the electron configuration as: </u>

1s^2 2s^2 2p^6 3s^2 3p^6 3d^{10}

Since, Cu^+ ion has the same configuration. The example of Nobel gas is, both InCl and InCl_3 are stable compounds. To form In^+ only the 5p^1 electron is removed leaving the [Kr] 5s^2 4d^{10} electronic configuration.

babymother [125]

Energy released from changing the phase of a substance from the gas phase to liquid phase can be calculated by using the specific latent heat of vaporization. The heat of fusion of water at 0 degrees Celsius is 40.7 kJ/mol. Calculation are as follows:<span> </span>


Energy = 27.9 g (1 mol / 18.02 g) x 40.7 kJ/mol


Energy = 63.09 kJ
