Question

a carbon isotope consists of 6 protons, 6 electrons and 8 neutrons. what is the mass number for this isotope? 8 12 14 6

Explanation:

Step1: Recall mass number formula

Mass number ($A$) is the sum of protons and neutrons, i.e., $A = \text{number of protons} + \text{number of neutrons}$.

Step2: Identify protons and neutrons

Given: protons = 6, neutrons = 8.

Step3: Calculate mass number

Substitute values: $A = 6 + 8 = 14$.

Answer:

14
