Explanation:
An alpha particle is a helium nucleus, 2 protons and 2 neutrons, loss of an alpha particle give a new element with an atomic number 2 less than the original isotope and an atomic mass that is lower by about 4 amu.
<h3>Sulfate takes two Copper atoms and gains negative valence charge,whereas the Copper gains a positive valence charge.The Sulfate is bonded in covalent bonds of polarity, Oxygen having the higher electronegativity, and therefore pulling the electrons closer to it's nucleus than to Sulfur's nucleus.</h3>
The chemical formula for sodium and sulfur is Na2S I believe...
