5. A chemical bond is an attraction between
atoms that allows the formation chemical
substances that contain two or more atoms .
The bond is caused by the electrostatic
force of attraction between opposite
charges, either between electrons and
nuclei, or as the result of a dipole attraction

7. Tro, Chemistry: A Molecular Approach
When metals bond to nonmetals, some electrons from
the metal atoms are transferred to the nonmetal atoms
–Metals have low ionization energy, relatively easy
to remove an electron from
–Nonmetals have high electron affinities, relatively
good to add electrons to
8. Electron from Na is
transferred to Cl, this
causes a charge imbalance
in each atom. The Na
becomes (Na+) and the
Cl becomes (Cl-), charged
particles or ions.
