Is lutetium a conductor of electricity?
What are the chemical properties of group 3 elements?
All the group 3 elements are rather soft, silvery-white metals, although their hardness increases with atomic number. They quickly tarnish in air and react with water, though their reactivity is masked by the formation of an oxide layer.
What are the chemical properties of radium?
Radium is silvery, lustrous, soft, intensely radioactive. It readily oxidizes on exposure to air, turning from almost pure white to black. Radium is luminescent, corrodes in water to form radium hydroxide. Although is the heaviest member of the alkaline-earth group it is the most volatile.
What is the hardness of lutetium?
Brinell hardness of Lutetium is approximately 900 MPa.
Is lutetium paramagnetic or diamagnetic?
Magnetic Type of the elements
| Hydrogen | Diamagnetic | Niobium |
|---|---|---|
| Zinc | Diamagnetic | Ytterbium |
| Gallium | Diamagnetic | Lutetium |
| Germanium | Diamagnetic | Hafnium |
| Arsenic | Diamagnetic | Tantalum |
What are the physical and chemical properties of Group 7 elements?
The group 7 elements exist as diatomic molecules . Their chemical formulae are F 2, Cl 2, Br 2 and I 2. The bond between the atoms in a molecule is very strong, but the forces of attraction between molecules are weak. This explains why group 7 elements have low boiling points.
Is radioactivity a chemical property?
Radioactivity – The emission of radiation from an atom with an unstable nucleus, is a chemical property.
Is Melting Point a physical property?
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
Is lutetium a reactivity?
Lutetium metal reacts with all the halogens to form lutetium(III) halides. So, it reacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to form respectively lutetium(III) bromide, LuF3, lutetium(III) chloride, LuCl3, lutetium(III) bromide, LuBr3, and lutetium(III) iodide, LuI3.
