Question

determine the number of neutrons in one atom of nickel. **you must round the atomic weight to the nearest whole number. then, subtract protons to get neutrons. nickel has ___ neutrons.

Explanation:

Step1: Find Nickel's atomic number

The atomic number of Nickel (Ni) is 28, so the number of protons is 28.

Step2: Round Nickel's atomic weight

Nickel's atomic weight is ~58.69, rounded to the nearest whole number is $59$.

Step3: Calculate number of neutrons

Subtract proton count from rounded atomic weight: $59 - 28 = 31$

Answer:

31
