Analyze the properties of a sodium atom and a sodium ion. What are the differences in mass, stability, and reactivity that are caused due to the differences between the sodium atom and sodium ion?

Answer 1

I don't intend to write a paper for you. The Na ion contains 1 less electron than the Na atom but both weigh essentially the same since the mass of an electron is so small. The Na atom has a neutral charge; the Na ion has a +1 charge.
You can complete from these basic facts.

Answer 2
