BeF4

In a world of atoms, so small and neat, There's one called beryllium, oh so sweet. With four fluorine friends, they gather 'round, Creating a shape, so perfectly sound. Tetrafluoroberyllate, a name quite long, But let's sing a song, and make it strong. With beryllium at the center, so bright, The fluorine atoms, shining with light. Just like sulfate, they're the same in size, With outer electrons, a wonderful prize. Langbeinites and Tutton's salts, you see, They're all like tetrafluoroberyllate, with glee. So let's remember this tale, oh so grand, Of beryllium and fluorine, hand in hand. In the world of atoms, they create, A tetrahedral shape, that's truly great. Random page: Se Eu Fosse Você
