this is how osmium appears in the periodic table. rounded to the nearest whole number, how many neutrons, on average, are in an atom of osmium? 76 os osmium 190.23 76 114 190 266

Answer

Explanation:

Step1: Identify atomic number and atomic mass

The atomic number of osmium is 76 (top - left number), and the average atomic mass is 190.23.

Step2: Recall the formula for number of neutrons

The number of neutrons $n$ is given by $n=\text{Atomic mass}-\text{Atomic number}$. Rounding the atomic mass to 190.

Step3: Calculate the number of neutrons

$n = 190 - 76=114$.

Answer:

114
