Someone. or something will get hurt
Not 100% sure if its right.
When an object covers equal distances in equal amounts of time, it is moving at a constant speed.
I believe that the answer is element
The radius of the electron's or basically the energy level for which the electron is found orbiting the nucleus of he hydrogen atom, as the principal quantum number tells us primarily the energy level that the electron will be found, is it the 1st, 2nd, and 3rd. The other quantum numbers tells us more specifically as per the subshell of the main shell the electron is in, the spin of the electron etc.
