Step 1:I'll solve this step-by-step using the precise LaTeX formatting guidelines:
Step 2:: Understand the given information
- Atomic number of titanium = 22 - Mass number of titanium = 48
Step 3:: Recall the relationship between atomic number, mass number, and neutron count
\text{Number of neutrons} = \text{Mass number} - \text{Atomic number}
The number of neutrons can be calculated by subtracting the atomic number from the mass number:
Step 4:: Calculate the number of neutrons
\text{Neutrons} = 48 - 22 = 26
Step 5:: Verify the calculation
- Atomic number (number of protons) = 22 - Number of neutrons = 26 - Mass number = 22 + 26 = 48 ✓
Final Answer
Key Insight: The number of neutrons in an atom is determined by subtracting the number of protons (atomic number) from the total number of nucleons (mass number).
