How is the sodium present in sodium chloride different from the sodium atom? Explain the difference between the sodium atom and the sodium ion. Make sure you include a discussion of the stability of the ions compared to the atom. *

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
