There is a few my science teacher told me there are many more.
If your older then grade 9 you may need a better answer XD hope this helps.
Radioactive elements.
Halogens have various practical uses, such as disinfectants (chlorine), in producing plastics (fluorine), in photography (bromine), and in water purification (iodine). They are also used in manufacturing medicines and chemicals.
Considering also very heavy artificial elements this group doesn't exist.
Hassium is a synthetic element that does not have any known practical uses. It is primarily used for scientific research purposes to study the properties of superheavy elements.
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
Please follow the links for some of the elements in the periodic table (link attached) and read the articles.
