Chlorine has two naturally occurring isotopes. What is the approximate natural abundance of
? – 24% – 35% – 50% – 76% Isotope Mass
34.97 u
36.97 u
The Correct Answer and Explanation is:
Correct Answer: 76%
Explanation:
The atomic mass of an element listed on the periodic table is the weighted average of the masses of its naturally occurring isotopes. This weighted average is calculated by multiplying the mass of each isotope by its fractional natural abundance and then summing these values. To determine the abundance
