The answer to this question is that two different neutral isotopes of
the same element will have the same atomic number. This is due to them
having the same number of protons, and it is these protons which

different masses due to a difference in the amount of neutrons.
Answer:
Bacteria that are non-controlled or destroyed by antibiotics are antibiotic-resistant bacteria. In the presence of an antibiotic, they will live and even develop. At least certain antibiotics can become immune to most infection-causing bacteria.
Explanation:
Some bacteria are immune to such antibiotics naturally. In most species found within the human digestive system, for example, benzylpenicillin has very little impact.
