(11) Indique cual de los siguientes modelos atómicos se ajusta más correctamente al modelo atómico de Thompson:..

(a) El átomo está formado por parejas de protones y electrones en igual número.

(b) El átomo está formado por una esfera maciza positiva rodeada de electrones en número tal que la
carga total sea neutra.

(c) El átomo es una esfera maciza positiva y con electrones en su interior en número tal que su carga
total sea neutra.

(d) El átomo está formado por partículas neutras fuertemente empaquetadas y que están constituidas
cada una de ellas por un protón y un neutron

the correct answer would be d. hope this !

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
