{{Main|Isotopes of titanium}}
Naturally occurring titanium is composed of five stable [[isotope]]s: <sup>46</sup>Ti, <sup>47</sup>Ti, <sup>48</sup>Ti, <sup>49</sup>Ti, and <sup>50</sup>Ti, with <sup>48</sup>Ti being the most abundant (73.8% [[natural abundance]]). At least 21 [[radioisotope]]s have been characterized, the most stable of which are [[titanium-44|<sup>44</sup>Ti]] with a [[half-life]] of 63 years; <sup>45</sup>Ti, 184.8 minutes; <sup>51</sup>Ti, 5.76 minutes; and <sup>52</sup>Ti, 1.7 minutes. All other [[radioactive]] isotopes have half-lives less than 33 seconds, with the majority less than half a second.<ref name="EnvChem" />

The isotopes of titanium range in [[atomic weight]] from {{val|39.002|ul=Da}} (<sup>39</sup>Ti) to {{val|63.999|u=Da}} (<sup>64</sup>Ti).{{AME2016 II|ref}} The primary [[decay mode]] for isotopes lighter than <sup>46</sup>Ti is [[positron emission]] (with the exception of <sup>44</sup>Ti which undergoes [[electron capture]]), leading to [[isotopes of scandium]], and the primary mode for isotopes heavier than <sup>50</sup>Ti is [[beta emission]], leading to [[isotopes of vanadium]].<ref name="EnvChem" />

Titanium becomes radioactive upon bombardment with [[deuterons]], emitting mainly [[positrons]] and hard [[gamma rays]].<ref name="LANL" />
