Answer:
C: electrons is the 3s orbital are higher than those in the 2s orbital
Explanation:
Looking at the options, the correct one is that the electrons in the 3s orbital will possess more energy than those in the 2s orbital. This is because the the 2s orbitals will be filled with electrons first before the 3s orbital.
Also from basics we know that the energy of an orbital increases as the quantum number increases.
Answer:

Explanation:
Hello!
In this case, given the relationship between velocity, wavelength and frequency:

By plugging in the given wavelength and frequency, we obtain the following speed:
