Question

current attempt in progress
your answer is partially correct.
how is it possible for there to be more than one kind of atom of the same element?
the properties of an element are related to the number of protons and electrons. if the number of neutrons differs, isotopes result. isotopes of an element are still the same element even though the atomic mass composition of the atoms are different.

Explanation:

Elements are defined by proton - electron count. When neutron numbers vary among atoms of the same element, isotopes are formed. Isotopes have different atomic masses but are still the same element.
