An atom made of 13 protons, 12 neutrons, and 13 electrons

Which of these two isotopes are heavier?

Answers

Answered by GPT-4o mini
To determine which isotope is heavier, we need to compare their atomic masses.

1. **Atom with 13 protons, 14 neutrons, and 13 electrons:**
- Number of protons = 13
- Number of neutrons = 14
- Atomic mass = 13 (protons) + 14 (neutrons) = 27

2. **Atom with 13 protons, 12 neutrons, and 13 electrons:**
- Number of protons = 13
- Number of neutrons = 12
- Atomic mass = 13 (protons) + 12 (neutrons) = 25

In conclusion, the first isotope (13 protons, 14 neutrons) is heavier, with an atomic mass of 27, compared to the second isotope (13 protons, 12 neutrons), which has an atomic mass of 25.
