Essay questions about atoms

Atom Y will receive the electron to form Y- ions, and attain the stable electron configuration with 8 electrons in the valence electron shell. Water was filled into the beaker. Less reactive i 1. Potential energy is energy that matter has due to its location or structure.

To attain the stable electron configuration with 8 electrons in the valence electron shell, atom X donates one electron to form a positive ion. Therefore, W is the most electropositive. One atom of Z contributes 4 electrons and each atom of Y contributes one electron.
