Best ResponseYou've already chosen the best response.1what do isotopes have to do with protons??

Best ResponseYou've already chosen the best response.0isotopes of an element are the same but weigh differently according to the number of neutrons. since thallium205 weighs more than thallium203 (since 205>203) there cannot be fewer protons, that would lead to a completely different element (since atomic number is the number of protons)

Best ResponseYou've already chosen the best response.0the atomic mass unit is an average of the thallium isotope number and how abundant it is in nature. Since the amu is closer to 205 than 203, you can infer that there is more thallium205. The number has nothing to do with weight.

Best ResponseYou've already chosen the best response.0the answer to number 6 is the second option because thallium always has an atomic number of 81 and the atomic number is equal to the number of protons, which is why you got number 9 wrong.

Best ResponseYou've already chosen the best response.0The atomic number of an element never changes because it represents the number pf protons. If you change the number of protons, you have a completely different element. As previously stated.
