How do you figure out how many electrons a sodium ion has? Can it be determined with a flame test?
Flame test does not in any way provides the number of electrons of sodium ion, but determines only the presence of that particular ion. The method is just a qualitative determination for the presence of ions in substances tested, though electrons are involved in the process, but quantity of it is beyond measurable.
The periodic table provides all the important information regarding elements. Remember that
Metallic is known to lose its valance electron to achieve the noble gas configuration that precedes it. While Nonmetallic substances are known to gain electrons to achieve stability. In this case, sodium is classified as a metal and thus loss its single valence electron to have the noble gas configuration to achieve stability; i.e.,
The decrease in number of electron of the latter is due to the fact that
