31, 31, 40. An atom of _31^71Ga has 31 electrons, 31 protons, and
40 neutrons.
The atomic number is 31, so the atom has<em> </em>31 protons (+).
If the atom is neutral, it must contain 31 electrons (-).
Mass number = protons + neutrons or
A = p + n
71 = 31 + n
n = 71- 31 = 40 neutrons
A is true of UV rays.
B is true not of UV rays but rather of visible light.
C is true not of UV rays but rather of microwaves. (unless you actually toast your toast in a toaster like a normal person)
D is true not of UV rays but rather of radio waves.
