Silver is an element, not a compound. 18 is True
19 is True. The number of protons determines the element. Electrons can come and go, and changing the number of neutrons just makes a different isotope of the same element. Change the protons, though, and it's a different element altogether.
Radon is also an element. One kind of atom.
Though, like all elements, it may have various isotopes. That is not usually counted as different atoms, however.
