Lawrencium (Lr) is an artificial chemical element, atomic number 103, solid, metal, period 7, the last element in the actinoids family, radioactive, unstable, obtained by nuclear reactions in particles accelerators.
Because lawrencium was obtained only in minutes amounts (1 000 - 2 000 atoms) the chemistry and physics of Lr are practically unknown. Lawrencium is trivalent in solutions and have now 11 isotopes. The longest half life is for Lr-266: 58 minutes. Some physical and chemical properties are only estimated.

What is the physical property of Lawrencium?
Lawrencium is a synthetically prepared element, a metal, has an atomic mas of 103, and is one of the Actinides.
Is lawrencium radioactive?
Lawrencium probably has some similar chemical properties as the other actinides; unfortunately no data now. Only the compound LrCl3 is known.
What are the chemical properties of lawrencium?
Lawrencium is an extremely radioactive element and is difficult to study due to its high radioactivity and short half-life. It is predicted to have similar chemical properties to other actinides, and it is expected to exhibit mainly a +3 oxidation state. Due to its limited availability and relatively short half-life, its chemical properties have not been extensively studied.
What are some properties of deuterium?
Deuterium, also known as heavy hydrogen, exhibits three separate properties: Physical properties, quantum properties and nuclear properties (the deuteron).
What are three physical properties used to identify compound?
melting point density and color

What are three physical properties of a bananna?
3 physical properties of a banana are that it is yellow, its shape is usually curvy, and that it feels kind of smooth. Remember: physical properties are things that you can observe without changing the matter.
What are the three physical properties of matter?
Three physical properties of matter are mass (amount of matter in an object), volume (the amount of space an object occupies), and density (mass per unit volume).
What are three different physical properties of ionic?
