Compare the mass of a proton to the mass of an electron.
Y_Kistochka [10]

Electrons are only about 0.054% as massive as neutrons and protons are only 99.86% as massive as the neutrons. The mass of the Proton is 1.67 x 10^-27 kg and the mass of the electron is 9.11 x 10^-31 kg. The mass of the electron is so much lighter than the mass of the proton.

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit ___?
Tju [1.3M]

Ans: As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit will <u>increase.</u>

The energy (E) is related to the frequency (ν) by the following equation:

E = hν

where h = planck's constant

The change in energy i between levels is:

ΔΕ = h(Δν)  -----(1)

Based on the above equation, as the changes in energy levels increase, the frequency of emitted radiation will also increase.
