The lighter elements have less protons and neutrons than heavier ones. It really is as simple as that
Almost all solid elements are heavier than air. This is why these elements do not float under normal atmospheric situations.

Cyclotrons can be used to create synthetic elements by bombarding a target element with high-energy particles such as protons or neutrons. This process can transmute the target element into a new, heavier element.
Gold is an element that is heavier than silver. It has a higher atomic number and greater density, making it denser and heavier per unit volume. Other heavier elements include platinum and mercury, which also exceed silver in terms of density and atomic mass.
I am not aware of any specific element "signaling" this. Towards the end of a stars life, however, relatively large amounts of heavier elements are produced.
Curium is one of the transuranic elements.

About 75% hydrogen and 25% helium, with some traces of heavier elements.

A heavy element is an element that based on the amount of metal that is in the element. Some can base the description of a heavier metal on the number of atoms but it is the amount of metal in the element.
Probably not. As of 2013, the last known element is #118. It is possible that additional elements will be discovered after that one. The heaviest stable element is lead, element #82. It is unlikely that any heavier element will be stable. In general, the tendency is for heavier elements to be less stable.

Older age might account for it. As a star ages, it uses up the simplest elements (hydrogen . . . helium . . .) then starts fusing heavier and heavier elements. Our Sun will get to the point of fusing iron, which is pretty heavy, but the truly large stars out there will fuse elements much heavier than Iron. These heavier and heavier elements may account for some stars having more complex elements in their spectra.

Technetium, Promethium, and all elements heavier than Bismuth.

All of them. There are no elements lighter than hydrogen. It has only two atomic particles, and you cannot have an element with less.
