i've got the same question as you in my textbook lol
Sodium metal is pure sodium and is made of sodium atoms.
Copper is a metallic element with the symbol Cu (29) and in its pure form contains only atoms of Copper. It is a pure substance. In addition, Copper is a soft metal and can be mixed with other metals to create alloys.
Potassium metal is a pure substance. In fact, it is an element as well. The reason potassium metal is an element is that it only contains one type of atom (all atoms of potassium have the same number of protons).
Iron is a pure metal.
Yes, the crystalline structure of zinc is hexagonal.
Sodium metal is pure sodium and is made of sodium atoms.
like this ::::::::::::: ::::::::::::: ::::::::::::: though a little closer. It depends on the metal, but atoms in a pure solid are tightly-packed into a crystalline structure. The shape of the crystal is dependent upon the atom.
Pure metal crystals have a regular and repeating atomic arrangement, known as a close-packed structure. They exhibit high thermal and electrical conductivity due to the free movement of electrons within the crystal lattice. Pure metal crystals are malleable, ductile, and have high melting points.
As a chemical element zinc contain only zinc atoms.
Yes.
Since it is a pure metal, hence an element, it exists as atoms.
A pure metal is just that; that metal, thus pure metals contain just one metal. For example aluminium foil contains just aluminium atoms. Alloys are one or more metals/elements that make up the metal, e.g C and Fe in steel.
Those are known as buckminsterfullerene or buckyballs, which are a type of fullerene molecule. They consist of 60 carbon atoms arranged in a hollow sphere resembling a geodesic dome, with a structure resembling the geodesic dome designed by architect Buckminster Fuller, hence the name. Buckyballs have unique properties and are a subject of scientific research for various applications.
Potassium metal is a pure substance. In fact, it is an element as well. The reason potassium metal is an element is that it only contains one type of atom (all atoms of potassium have the same number of protons).
Buckyballs
C. Diamond is carbon in a pure form, a network of just carbon atoms
Iron is a pure metal.
