Using your data compare atomic number with total number of spectral lines. Is there a pattern? What might explain the presence or absence of a pattern based on what you know about atoms, electrons, and emission spectra? (I'm greatly sorry if the data is wrong and or confusing I'm trying my best here, I just need help with two questions. I will send the second one after this is answered)

What statements accurately describe atoms

In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall. the cylinder begins to rotate about a vertical axis. then the floor on which the passengers are standing suddenly drops away! if all goes well, the passengers will “stick” to the wall and not slide. clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. part a what is the minimum rotational frequency, in rpm, for which the ride is safe? express your answer using two significant figures. f f = rpm
