Question

which of the following elements are in the compound: *

oxygen (o) and nitrogen (n)

potassium (k) and oxygen (o)

carbon (c) and oxygen (o)

Explanation:

In the chemical formula \(K_2O\), \(K\) represents potassium and \(O\) represents oxygen. There is no nitrogen (\(N\)) or carbon (\(C\)) in this compound. So the elements in \(K_2O\) are potassium (K) and oxygen (O).

Answer:

Potassium (K) and Oxygen (O)
