1. Introduction to Pennium
Pennium is a synthetic element with the atomic number 106 and the symbol Pn. It is located in Group 6 (the chromium group) of the periodic table. Pennium isotopes are variations of the element pennium that have different numbers of neutrons in their nuclei.
The different isotopic compositions affect the properties of pennium.
Isotopes are atoms of the same element that have the same atomic number but different mass numbers. This means that they have the same number of protons in their nuclei, but different numbers of neutrons. The mass number is the sum of the number of protons and neutrons in the nucleus.
2. Known Isotopes of Pennium
There are currently 20 known isotopes of pennium, ranging in mass number from 253 to 272. All pennium isotopes are radioactive, with half-lives ranging from a few milliseconds to several days. The longest-lived isotope of pennium is 261Pn, with a half-life of 26.3 minutes.
| Isotope | Mass Number | Half-Life | Decay Mode |
|---|---|---|---|
| 253Pn | 253 | 3.3 ms | α decay |
| 254Pn | 254 | 6.3 ms | α decay |
| 255Pn | 255 | 15 ms | α decay |
