Titanium is well known for being one of the least dense, strong, and corrosion-resistant elements, and as such has many applications, especially in alloys with other elements, such as iron. Germanium is fairly rare on earth, leading to its comparatively late discovery. Krypton, like most noble gases, is also used in lighting because of its many spectral lines and the aforementioned reasons. Vanadium is never found in pure form in nature, but is commonly found in compounds. For example, it will be solid on a typical spring day, but will be liquid on a hot summer day.
