Answer :
Sure, let's solve the problem step-by-step:
1. Identify the Number of Protons, Electrons, and Neutrons:
- The element has 24 protons, 24 electrons, and 28 neutrons.
2. Determine the Atomic Number:
- The atomic number of an element is the number of protons. Here, the atomic number is 24.
3. Determine the Mass Number:
- The mass number is the sum of protons and neutrons.
- Mass number = Number of protons + Number of neutrons
- Mass number = 24 + 28 = 52
4. Identify the Element:
- The element with atomic number 24 is Chromium (symbol: Cr).
5. Write the Symbol for the Element:
- The notation for an element generally follows this format: [tex]\[ \text{{mass number}} \ _{\text{{atomic number}}} \ \text{{Element symbol}} \][/tex]
- For this problem, it becomes [tex]\[ {}_{24}^{52} \text{Cr} \][/tex]
6. Match the Answer with the Given Options:
- The correct notation [tex]${}_{24}^{52} \text{Cr}$[/tex] matches option b.
So, the correct answer is:
b. [tex]\( {}_{24}^{52} \text{Cr} \)[/tex]
