Neither, it is a crystalline solid in pure form.
monatomic
All diatomic elements contain pure covalent bonds because theyre of the same elements.
The pure element has no odor as it is a solid and nonvolatile.
Fluorine is a gaseous element which exists as diatomic molecules and every element is a pure substance.
Pure, elemental sodium is neither. Any element in its elemental form has no bonding unless it's a diatomic molecule such as Hydrogen, H2, or a covalent network such as some forms of carbon, in which case that would be a covalent bond.
monatomic
Germanium is a naturally occurring element, but does not occur in pure form on the Earth (only in compounds).
No, although it ionizes in water it is composed of diatomic molecules in its pure form.
Pure germanium is obtained by distllation of germanium tetrachloride, followed by hydrolysis of GeCl4 to GeO2 and reducing of GeO2 with hydrogen to Ge.
Yes. Pure gold is a much better conductor than pure germanium is.
silicon and germanium
Fluorine (atomic symbol F) is an element. In its pure form it is a gas: F2, a diatomic molecule.
If you mean F2 (fluorine), it is a diatomic molecule of the element fluorine. It's the common form of pure fluorine, since the halogen elements are all diatomic molecules.
All diatomic elements contain pure covalent bonds because theyre of the same elements.
Pure iodine at room temperature is a highly volatile solid.
Pure germanium is neither n or p. When doped with impurities it can be either.
in pure germanium there are effectively noconduction band electrons or holes, so they don't move at all.
