Representative for a chemical element is the number of protons.

Atoms do have the same properties as long as stable form of its corresponding element is not a molecule. For example H1 (Hydrogen) which is a single atom has the same properties that of Hydrogen as it doesn't require to be in a molecular form to be stable. On the other hand O1 (Oxygen) doesn't have the same properties as Oxygen that we breathe as that Oxygen is actually O2 which is actually necessary for it to remain stable.
The items that contain more than one element and have metallic properties are known as alloys. They can be an intermetallic compound that lacks phase boundaries, a metallic phase mixture, or a solid element solution.

Reptiles are more closely related to mammals.
are salamanders or snails closely related to an octupus
the grasshopper is more closely related to the housefly.
No element contains more than one element.
The properties of nonmetals also tend to vary more from and element to element than do the properties of the metals
A cod is much more closely related to a shark than to a human.
Deer and cattle are more closely related than goats and cattle.
Actually, echinoderms are more closely related to humans than molluscs.
