Final answer:
Option B: The compound K₂O is correctly named as potassium oxide. It is an ionic compound made up of K+ and O2- ions.
Step-by-step explanation:
The compound represented by the equation K₂O is known as potassium oxide. This is an ionic compound formed through the ionic bond between potassium and oxygen. Potassium forms a positive ion shown as K+, while oxygen forms a negative ion shown as O2-. When these two ions bond, they form potassium oxide, which is the correct name for the compound K₂O.
The compound represented by the equation K₂O is potassium oxide. In this ionic bond, potassium gives away 2 electrons and becomes K+, while oxygen accepts 2 electrons and becomes O²-. The positive and negative ions attract each other, forming an ionic bond and creating the compound potassium oxide (K₂O).
