Answer:
K2O
Explanation:
The compound potassium oxide is an ionic compound .The compound consist of 2 atom of potassium and 1 atom of oxygen. Ionic compound have both cations and anion. In an ionic compound their is a transfer of electron. One specie donates electron(s) while the other receives the electron(s). The cation loses electron(s) while the anion receives electron(s).
The compound can be represented as follows:
Potassium usually possess charge of +1 , K+ while oxygen possess charge of 2- , O2- .
K+ and O2-(The charge are superscript)
cross multiply the charge to get the chemical formula
K2O
From the chemical formula above one could understand that 2 atoms of potassium donates 1 electron each to the oxygen atom for both atoms(oxygen and potassium) to fulfill the octet rule.
