Question

Matter is made of atoms that have positive centers of neutrons and protons surrounded by a cloud of negatively charged electrons. This statement is
A a theory
B a hypothesis
C an inference
D an observation

Answer 1

i am going to guess it's a hypothesis, because the statement does not mention any experiments that back it up.

Answer 2

it's not an observation, because observations refer to experimental data.

Answer 3

it's not an inference, because the statement does not contain a premise. it's just a conclusion.

Answer 4

it could be a theory, because this statement explains chemical phenomena, and it is supported by considerable amount of evidence.

Answer 5

in any case, a theory is just a hypothesis that has stood the test of many experiments. we call newton's mechanics a theory even though it's been proven to be wrong (by Einstein).

Answer 6

It's a theory.
