검증된 단계별 안내1
Identify the element symbol given, which is Ti for titanium.
Recall that the number of protons in an element is equal to its atomic number, which is unique for each element.
Look up the atomic number of titanium (Ti) on the periodic table; this number represents the number of protons.
Understand that the number 48 in 48Ti represents the mass number (protons + neutrons), not the number of protons.
Conclude that the number of protons in the isotope 48Ti is the atomic number of titanium, which is 22.
