...says that the configuration 1s^2, 2s^2, 2p^5, 3s^2, 4p^1 represents an excited atom. Please explain!

An excited atom is one in which an electron has jumped up into the next highest energy level in this case the atom has gone from the elctron configuration of 3s^3 to3s^2 and 4p^1 the excited electron has moved from the 3s orbital to the 4p orbital causing the excited state.

The configuration should be 2 p^6 3s^2; the excited electron moved from the 2 p^6 to 4p^1.
At any rate the reason (defined) for excited is an electron has been raised to a higher orbital and is less stable.

1s2 2s2 2p6 3p1 The ground state configuration of the sodium atom is 1s2 2s2 2p6 3s1, as deduced from the Aufbau principle . The first excited state is obtained by promoting a 3s electron to the 3p orbital, to obtain the 1s2 2s2 2p6 3p1 configuration
