Answer:
B. X-rays
Explanation:
From the given choices, x-rays will have the highest energy of the given waves.
The energy of electromagnetic waves is highly dependent on their frequency and wavelength.
Electromagnetic waves with a high frequency and small wavelength will have higher energy compared to those with low frequency and high wavelength.
X-rays are one the most energetic waves on the periodic table. They have a very high frequency and low wavelength.
Since energy cannot be created nor destroyed, the change in energy of the electron must be equal to the energy of the emitted photon.
The energy of the emitted photon is given by:

where
h is the Planck constant
f is the photon frequency
Substituting

, we find

This is the energy given to the emitted photon; it means this is also equal to the energy lost by the electron in the transition, so the variation of energy of the electron will have a negative sign (because the electron is losing energy by decaying from an excited state, with higher energy, to the ground state, with lower energy)
Well it occurs in igneous, metamorphic, and sedimentary rocks.
quartz is a mineral, not a rock.
it is abundant or in other words rich.
Yes because mercury has more protons and electrons that tin. (30 more)
