For every o ion, two na ions are needed to balance charges. which ratio represents the relationship between na and o? 1 na: 1 o 1 na: 2 o 2 na: 1 o 2 na: 2 o

For every O ion, two Na ions are needed to balance charges. Which ratio represents the relationship between Na and O?

2 Na:1 O

Ratio represents the relationship between Na and O is 2:1.

Explanation:

Given that for every oxygen ion two sodium ions are needed to balance charge.

1 oxygen ion requires 2 sodium atoms

The ratio of oxygen ion to sodium ions is:

So, on reversing the ratio we will get the ratio of sodium ions to oxygen ions:

option number c is the right answer.
