Given below are two statements:

Statement I:	Atoms are electrically neutral as they contain equal number of positive and negative charges.
Statement II:	Atoms of each element are stable and emit their characteristic spectrum.

In the light of the above statements, choose the most appropriate answer from the options given below:

1.	Both Statement I and Statement II are incorrect.
2.	Statement I is correct but Statement II is incorrect.
3.	Statement I is incorrect but Statement II is correct.

A model for the quantized motion of an electron in a uniform magnetic field states that the flux passing through the orbit of the electron is where is an integer, is Planck's constant and is the magnitude of the electron's charge. According to the model, the magnetic moment of an electron is its lowest energy state will be ( is the mass of the electron):
