There is an electroststic force between nucleus and electrons. Hydrogen, Lithium, and sodium all being in the same column on the table have the same amount of atoms in their outer field.
Figure b For aqueous solution: 1. The X ion will attract Y ion with strong electrostatic force and form an ionic compound with the formula XY.
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.
The electrons are located outside the nucleus inside orbitals. With all that scientists know about atoms, molecules, and elements I am sure there is much more to learn. This means that during the course of a reaction, mass is also conserved.
