Question

What two ions are represented on the left side of the screen?

A) Sodium (Na+) and Chloride (Cl-)
B) Calcium (Ca2+) and Hydroxide (OH-)
C) Potassium (K+) and Nitrate (NO3-)
D) Magnesium (Mg2+) and Sulfate (SO42-)

Answer 1

The two ions discussed are sodium (Na+) and chloride (Cl-), which together form sodium chloride (NaCl), or table salt, with a 1:1 ratio.

Step-by-step explanation:

The question is asking which two ions are represented on the left side of the screen out of the given options. The correct answer is not provided in the options above; however, it seems the ions being discussed are sodium (Na+) and chloride (Cl-), making up sodium chloride, which is table salt and has a 1:1 ratio. When writing ionic compounds, we use the lowest whole number ratio and write the formula for the cation first followed by the anion without showing the charges in the formula. For NaCl, one sodium ion pairs with one chloride ion to balance the charge, leading to the formula NaCl.
