There are lots. Here are five: density, melting point, boiling point, freezing point, Atomic Mass
H2 is a molecule of hydrogen, which is an element. In nature, hydrogen exists as a molecule, with two atoms combined. H2 and H have identical properties because only one element is represented in their atomic structures. I hoped this helped you!
The smallest unit of an element that maintains the properties of that element is the atom.
The element that would have properties most similar to the new element would be an element that lies in the same group as the new element. Specifically, the element with the most similar properties will lie directly above or below that element in the group.
there is no such element
It is helpful to identify an unknown element when you are exposed to a lot of it. This element could be very dangerous to you.
The properties of nonmetals also tend to vary more from and element to element than do the properties of the metals

The physical properties of a pure substance can be used to identify it. A pure substance is an element or a compound, not a mixture.
Atoms are considered the smallest particle of an element because if we subdivide an atom, we loose the chemical and physical properties of that element. The things that identify that atom as an atom of a given element will disappear.
Pure barium is very hard to prepare, to the extent that many of its properties are unknown. The these circumstances it is difficult to identify the uses of the pure element.

The smallest unit of an element that maintains the properties of that element is the atom.
The atom is the smallest unit of an element that has all the properties of the element.
when a substance can not be chemically reduced
Elements in the same family, or group, have similar physical and chemical properties.
The element that would have properties most similar to the new element would be an element that lies in the same group as the new element. Specifically, the element with the most similar properties will lie directly above or below that element in the group.
there is no such element
