#2: What do we now call the negative particles that Thomson said were parts of all atoms? A. protons B. neutrons C. electrons D. cathode rays **Not quite sure... :( Either B or C but idk for sure which one :(
hey! what do u think?? :D is #1 A. John Dalton?? and what bout #2??
You got the first one, as for the second one, remember that Protons are positively charged particle. Neutrons, as the name implied, has no charge. Electrons will be the opposite of protons, negatively charged.

ohhh i see :) so my answer for #2 is C. electrons???
and does it look like #3 is correct?? :D
oh and #4 lol :) i think i got this one right too, but not 100% sure :P #4: Who discovered the electron? A. John Dalton B. Antoine Lavoisier C. Robert Millikan D. J.J. Thomson ***My answer : D. J.J. Thomson is that right?? :)
what do y'all think of #3 and #4??? :)
so far we have #1: A. John Dalton #2: C. electrons but did i get #3 and #4 right?? :D
You're right for Number 2, as for Number 3 is about the Milikan oil drop experiment and the charge on an electron is negatively charged which causes rise and fall by changing the voltage across the plates.
so #3 is C. mass of an electron??
and #4, did i get that right?? is it D. JJ Thomson??
Number 4 is D, you just memorize it.
