station 8\niron atom: 26 protons, mass number 56.\n1. how many electrons does fe³⁺ have?\n2. how many neutrons are in this isotope?
Answer
Explanation:
Step1: Determine electrons in neutral iron
A neutral iron atom has the same number of electrons as protons. Given iron has 26 protons, a neutral Fe atom has 26 electrons.
Step2: Calculate electrons in Fe³⁺
Fe³⁺ has a 3 - plus charge, meaning it has lost 3 electrons. So the number of electrons is $26 - 3=23$.
Step3: Determine number of neutrons
The mass number is the sum of protons and neutrons. Given mass number = 56 and number of protons = 26, the number of neutrons is $56 - 26 = 30$.
Answer:
- 23
- 30
