We will talk about metals that are inert under normal conditions, which is why their shine does not fade over the years. They also have very high melting points. Thus, thanks to titanium, man was able to pass the supersonic barrier and conquer space. It is part of aircraft alloys. The other two elements are extremely important for nuclear energy. All of them are in the 4th group of the periodic table, which is also called the titanium subgroup. The presenter will analyze the properties of these elements in detail. #chemistry #experiments #experiment
