Significados de actinides en inglés

For both actinides, like-for-like An-O → An-N substitutions lead to improved reaction energies.

But it's the strange behavior of those nuclei that has long made actinides the stuff of wonder.

At intervals that can vary from every millisecond to every hundred thousand years, actinides spin off particles and decay into more stable elements.

Actinides are dense because their nuclei contain large numbers of neutrons and protons.

Actinides are the only materials that split apart this way, and if the collisions are uncontrolled, you unleash hell: a nuclear explosion.
