Question

Dalton hypothesized that atoms are indivisible and that all atoms of an element are identical. It is now known that _____. (1 point)

A. all of Dalton's hypotheses are correct
B. atoms of an element can have different numbers of protons
C. atoms are divisible
D. all atoms of an element are not identical but they must all have the same mass

Answer 1

atoms are divisible, they're made of subatomic particles: electrons, neutrons, and protons.. which are made of smaller particles quarks, leptons..

Answer 2

Its not B because if you change the number of protons then it becomes a totaly different element. IT IS NOT C. ATOMS ARE NOT DIVISISIBLE. If they were divisisble then that means it would be able to break down into something smaller. An atom is the smallest unit of measure in chemistry. The answer is D because diiferent atoms within a element can have a different number of nuetrons. For example Lead-33 and Lead-34 are the same element but one has one more nuetron than the other.

Answer 3

atoms ARE divisible, homie. you just mentioned that they're made of smaller particles (neutrons and protons) so how can you deny that they're divisible? *FACEPALM*

Answer 4

Hahaa okay well thanks for the answer c:
