Answer : The charge of cesium is, (+1)
Explanation :
Oxidation state or number : Oxidation state represent the number of electrons gained or lost by the atoms of an element in the compound. That means it also tells us about the charge present on the cation and the anion.
Oxidation state or number are generally written with the sign (+) and (-) first and then the magnitude.
When the atoms are present in their elemental state then the oxidation number will be zero.
Oxidation number of oxygen (O) in compounds is usually equal to (-2).
The given chemical formula of cesium oxide is, [tex]Cs_2O[/tex]
Let the oxidation state of 'Cs' be, 'x'
[tex]2x+1(-2)=0\\\\2x-2=0\\\\x=\frac{2}{2}\\\\x=+1[/tex]
Therefore, the charge of cesium is, (+1)
