Answer:
The correct answer, the charge of Cesium is +1
Explanation:
Hi!
Let's solve this!
The compound is: Cs2O.
We know that the oxygen valence number is -2.
We also know that the compound has to be balanced, so to balance the charges we need +2. As there are two Cs, we perform the following operation:
2 * (+ 1) -2 = + 2-2 = 0
We conclude that the correct answer, the charge of Cesium is +1
