Final answer:
Option A. The total number of protons in titanium is always 22 as it is its atomic number. The number of neutrons can vary depending on the isotope, but the most common isotope of titanium has 26 neutrons. So the correct answer is (a) Protons = 22, Neutrons = 24.
Step-by-step explanation:
The question asks to determine the total number of protons and neutrons in titanium. The atomic number of titanium, which represents the number of protons, is 22. This is a fact and doesn't change for any titanium atom as it defines the element. To find the number of neutrons, you need to know the specific isotope of titanium you're considering, as this can vary.
However, the most common isotope of titanium has an atomic mass of 48. As the number of protons is 22, the number of neutrons is calculated by subtracting the atomic number from the atomic mass (usually the closest whole number to the standard atomic weight). Thus, for the common isotope of titanium: Neutrons = Atomic mass - Atomic number = 48 - 22 = 26.
Therefore, the correct option, which lists the number of protons and neutrons in titanium is:
- (a) Protons = 22, Neutrons = 24
