write the nuclear symbol dor an isotope with 6 more neutrons and 3 more protons than chromium-53
The Correct Answer and Explanation is:
The isotope you’re describing has 6 more neutrons and 3 more protons than chromium-53. Chromium-53 (Cr-53) has the following nuclear properties:
- Protons (atomic number): 24
- Neutrons (mass number – atomic number): 53 – 24 = 29
Now, adding 3 more protons and 6 more neutrons:
- Protons: 24 + 3 = 27 (This changes the element to Cobalt (Co), since cobalt has an atomic number of 27.)
- Neutrons: 29 + 6 = 35
- Mass number: Protons + Neutrons = 27 + 35 = 62
Thus, the isotope is Cobalt-62. Its nuclear symbol would be written as:Co6227\text{Co}_{62}^{27}Co6227
Explanation:
The atomic number (27) tells you the number of protons, which uniquely identifies the element as cobalt. The mass number (62) is the sum of the protons and neutrons. In this case, 3 additional protons make the element cobalt instead of chromium, and 6 more neutrons result in a mass number of 62. The nuclear symbol represents the element’s identity and the total number of nucleons (protons and neutrons) in the nucleus, with the atomic number written as a subscript and the mass number as a superscript.
So, the nuclear symbol for this isotope is Co-62 or written in full as 2762Co_{27}^{62}Co2762Co.
