i've got the same question as you in my textbook lol
Sodium metal is pure sodium and is made of sodium atoms.
Buckyballs
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.
Each individual pure metal crystal is characterized by its individual properties. Arrangement of metals in the metal structure is dependent on its characteristics.
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.
Buckyballs
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.
