What experimental evidence led to the development of this atomic model from the one before it? 1.) a few of the positive particles aimed at a gold foil seemed to bounce back off of the thin metallic foil. 2.)experiments with water vapor showed that elements combine in specific proportions. 3.)equations were used to identify regions around the nucleus where electrons would likely be. 4.)cathode rays were bent in the same way whenever a magnet was brought near them.

It doesn’t seem like you’ve attached a picture of the model in question. What I can tell you is that the answer is 1 is the picture is of Rutherford model (most of the atom is empty spaced with a small, dense, positively charred nucleus), the answer is 3 is it is the modern model (the electrons are in a cloud around the nucleus) and the answer is 4 is it is Thompson’s plum pudding model (the electrons are wedged into a positively charged atom) what I can tell you with absolute certainty is the the answer is not 2

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
