Source-derived summary

Naturally occurring vanadium (23V) is composed of one stable isotope, 51V, and one radioactive isotope, 50V, with a half-life of 2.71×1017 years. Twenty-five artificial radioisotopes have been characterized, ranging from 43V to 68V. The most stable of these are 49V with a half-life of 330 days and 48V with a half-life of 15.9735 days. All of the remaining radioactive isotopes have half-lives shorter than an hour, with the majority of them below 10 seconds. Seven metastable excited states have also been observed, two of which are for 60V.

The primary decay mode before the most abundant stable isotope 51V is electron capture or positron emission resulting in titanium isotopes; that after the beta decay to chromium isotopes.

Editorial summary

The public source identifies “Isotopes of vanadium” as naturally occurring radioactive isotope. This brief keeps that definition visible, then builds a research path around Isotopes, vanadium and naturally.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1017, 2009—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Isotopes, vanadium and naturally providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Isotopes of vanadium”, the useful work is to connect “naturally occurring radioactive isotope” to the records capable of establishing context and consequence.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 19, 2026. The linked authority identifier is Q477795. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1017 and 2009.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
