    $\begingroup$ Promethium sticks out much more in the PSE than astatine. Actinium, francium, protactinium are also very unstable compared to their neighbours. An odd number of protons is often not very favourable. But really this is no chemistry question. $\endgroup$ – .

The most stable of them is promethiumm, with a half-life of days; this is longer than the half-lives of the ground states of all promethium isotopes, except for promethium to In fact, promethiumm has a longer half-life than its ground state, promethiumPronunciation: /proʊˈmiːθiəm/ ​(proh-MEE-thee-əm).

The reason Tc and Pm can end up with no stable isotopes is because they are of odd atomic number. This is only part of the reason to why. The full answer is really quite complicated so bear with me. If you take shell effects into consideration, yo.

This course provides the students with the knowledge of nuclear properties, and inorganic analytical chemistry of all known radioactive elements. The students will acquire competence to get oriented in the field of the properties, behaviour, and analytical procedures of all known radioactive elements.

Promethium (formerly prometheum) is a chemical element with symbol Pm and atomic number All of its isotopes are radioactive; it is one of only two such elements that are followed in the periodic table by elements with stable forms, a distinction shared with ally, promethium is a lanthanide, which forms salts when combined with other elements.

(In other words, 7 hours is the half-life of astatine.) A similar supply of francium would be half-depleted in 20 minutes. So common sense says that francium should be rarest.
