Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. H. He. Use your knowledge of periodic trends to predict which element reacts most vigourosly with water to produce hydrogen gas. Fr. You can edit the radius of atoms of that element type using the radius field "r [Å] ". Its melting point is 83.19 degrees Fahrenheit. True. Be Ca Mg Sr. Sr. Which family of elements loses its valence electrons most easily? Differentiating electrons enters into same shell hence the effective nuclear charge decreases .
