Protactinium is actually a substance ability with atomic matter 91 which means that you’ll find 91 protons and you will 91 electrons in the atomic structure. Thorium try a chemical function with atomic matter 90 meaning that you will find 90 protons and you can 90 electrons regarding the atomic framework. Actinium is a delicate, silvery-light radioactive material. Actinium are a chemical function that have nuclear number 89 which means that you can find 89 protons and you will 89 electrons on the nuclear framework. Lutetium are a great silvery light metal, and therefore resists corrosion within the inactive heavens, however in the wet sky.
