Question

determine the number of neutrons in one atom of carbon. you must round the atomic weight to the nearest whole number. then, subtract protons to get neutrons. carbon has _ neutrons. question 13 0.5 pts determine the number of neutrons in one atom of hydrogen. you must round the atomic weight to the nearest whole number. then, subtract protons to get neutrons. hydrogen has _ neutrons.

Explanation:

Step1: Get carbon's atomic data

Carbon's atomic number (protons) = 6; atomic weight ≈ 12.01, rounded to 12.

Step2: Calculate carbon's neutrons

$\text{Neutrons} = 12 - 6 = 6$

Step3: Get hydrogen's atomic data

Hydrogen's atomic number (protons) = 1; atomic weight ≈ 1.008, rounded to 1.

Step4: Calculate hydrogen's neutrons

$\text{Neutrons} = 1 - 1 = 0$

Answer:

Carbon has 6 neutrons.
Hydrogen has 0 neutrons.
