A chemist mixes two substances together blue powder with no smell in the color us liquid with a strong smell the repeating groups of atoms are shown above on the left after they were mixed this summer analyze the results and found two substances one ending substance that the repeating groups of atoms shown above on the right is the ending the same substance as Looper what happened to atoms of the starting substance when the ending substance formed be sure to explain your answers to both of these questions

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
