pyromorphite · Answer

atomic weight = 197 symbol = Au electrons = 79 
 neutrons = 197 - 79 = 118 
 answer: E

Anonymous · Answer

The element with an atomic weight of 197, specifically gold (Au), has 118 neutrons. This is calculated by subtracting its atomic number (79 protons) from its mass number (197). Hence, the correct option is e. 118.
