How are a sodium atom and a sodium ion alike?

They are not allike as na atom has 11 elctrons and Na ion has 10 electons. They both have the same nucleus (same number of protons and neutrons). The only difference is that the ion has one less electron than the atom (in this case).

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

The answer to this problem is. 67
