They have different numbers of protons
Each type of media has its own unique set of elements that producers can use
100 exactly
The element with atomic numbers 43 (Technetium) and 61 (Promethium) are unique because they are the only radioactive elements before the start of the bulk of the radioactive elements. The bulk of the radioactive elements begins at atomic number 84 (Polonium). These are significant as they aren't primordial and are only found due to radioactive decay.
as it has only one proton and electron and no neutrons
The element carbon is unique because it has four valence electrons, allowing it to form four bonds with other molecules. It also is unique in the sense that it can bond with other carbons, something most other elements cannot do.
No elements are unique to China
Pnictogen are the chemicals in group 15. What is unique about pnictogen elements is that it is made of covalent compounds and have unusual bonding properties.
