Question

HELP!!!! An element with 60 protons and a mass of 260 would be considered:

a. stable
b. radioactive
c. nonexistent

Answer 1

Step-by-step explanation:

An element with 60 protons and a mass of 260 would be considered nonexistent.

In nature, elements with atomic numbers (number of protons) up to 92 (uranium) can exist. However, an element with 60 protons does not occur naturally. Elements with atomic numbers higher than 92 are typically synthetic and created in a laboratory setting.

Therefore, the element described with 60 protons and a mass of 260 would be considered nonexistent in nature.
