An electron in the n=7 level of the hydrogen atom relaxes to a lower energy level, emitting light of 1005 nm. part a what is the value of n for the level to which the electron relaxed? express your answer as an integer.

final relaxed state is m = 3

Explanation:

As we know that due to transition of electron the wavelength emitted is given as

now we know that

now we have

now by solving above equation for m we will have

m = 3

so the final relaxed state is m = 3

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
