WebA horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right. Block. Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). WebAnswer (1 of 3): Francium is radioactive, with a short enough half-life that it's not really possible to produce that millimeter cube. If you did magically produce one and proceed to lick it, you'd get a significant dose of radiation to the face. If you managed to do this quickly enough, some of ...
