The mechanical properties of actinium are not determined.
Actinium is a metal because has metallic bonds and the properties of a metal.
- the electronegativity of actinium is 1,1- actinium is trivalent (excepting in AcH2)- actinium react easily with oxygen, halogens, water vapors, acids
Chemically, actinium is similar to lanthanum. Actinium react with halogens (F, Cl, Br, I), oxygen, sulphur, etc.
Well, honey, actinium is not magnetic. It's a radioactive element that doesn't have magnetic properties. So, if you were planning on sticking a magnet to it, I hate to break it to you, but it ain't gonna work.
Melting point of actinium: 1 050 0C Boiling point of actinium: 3 198 0C
Lanthanum and actinium have different properties. So, they are kept apart from the periodic table.
Not soluble in water (probably only a slow reaction), soluble in acids.
Actinium is not commonly used in agriculture due to its radioactive properties and potential health hazards. While it can be beneficial as a radiation source for research, its use in agriculture is limited by the risks associated with its emission of alpha particles. Overall, the disadvantages of using actinium in agriculture outweigh any potential benefits.
physical
Actinium is a trivalent metal; only in the actinium hydride is divalent.
Actinium may be used in actinium-beryllium neutron sources or in radiotherapy.
