Question

describe the changes in appearance of the substances when sodium and chloride combine to form sodium chloride.

Answer 1

Answer:

When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. ... In the first video clip, the sodium flares up almost immediately upon reaction with the water, and "burns out" quickly.
