Question

question 6 (5 points) listen an atom has 35 protons, 35 neutrons, and 35 electrons. whats the estimated mass of the atom? a) 38 b) 73 c) 35 d) 70

Explanation:

Step1: Recall atomic mass estimation

The estimated mass of an atom is approximately the sum of protons and neutrons (electrons have negligible mass).

Step2: Calculate sum of protons and neutrons

Protons = 35, Neutrons = 35. So mass ≈ 35 + 35 = 70.

Answer:

D) 70
