n1 is the first enegry level so does that mean n2 =2?
n
1 is the first energy level, and n
2 is the second energy level.
i know what n is i just dont understand why n has different values and when they should be different.
Well, think of it this way.
The second energy level, is not the same as the first, otherwise they wouldn't call it the second energy level, right?
If that's the case, it has to have either a higher or lower energy, right?
Since we're talking about n
1, which is the lowest energy state of an electron in an atom, n
2 has to be higher in energy, right?
