part a\nwhat is the atomic mass of an atom that has 6 protons, 6 neutrons, and 6 electrons?\n18\n12\n6\n8
Answer
Explanation:
Step1: Recall atomic mass formula
Atomic mass = Protons + Neutrons.
Step2: Substitute given values
Given 6 protons and 6 neutrons. So, Atomic mass = 6 + 6.
Step3: Calculate result
6+6 = 12.
Answer:
B. 12
