True or false a molecule with more than one kind of atom will be listed on the periodic table?
The answer to this question depends on the unstated definition of "kind of atom". All atoms of one element have the same atomic number, which equals the number of protons in nuclei of the atoms. However, atoms of the same element may have different masses because of different number of neutrons in their nuclei.
Why is gold considered as an element and an atom at the same time?
An element is a substance that cannot be broken down into simpler substances. An atom is a single piece of an element. If you break an atom apart, you no longer have that substance.
