Read about restoring electrolytes on page r4 of the element handbook. write electron configurations for the two principal ions found in body fluids.

The two principal ions found in body fluids are Na(+) and Cl(-).

Na(+) is the cation formed when Na loses one electron. So, given that the atomic number of Na is 11, the number of electrons of Na(+) is 11 - 1 = 10.

Cl(-) is the anion formed when Cl gains one electron. So, given that the atomic number of Cl is 17, the number of electrons of Cl(-) is 18.

Now let's do the electron configuration of each ion.

Na(+): 10 electrons =>



Cl(-): 18 electrons =>

Its a hope this
