Question

what value is closest to the mass of the atom? 4 amu 6 amu 10 amu 14 amu

Explanation:

Step1: Know atomic mass composition

Atomic mass is mainly determined by protons and neutrons. Protons and neutrons have a mass of approximately 1 amu each.

Step2: Count protons and neutrons

Count the number of particles in the nucleus (protons and neutrons). Assume red spheres are protons, blue are neutrons. Counting them gives a total of 10 particles in the nucleus.

Answer:

10 amu
