Sodium (P) and Potassium (Q) are electrolytes in the fluid outside and inside your cells. The balance between these particles contributes to maintain your body’s energy. P combines with element with atomic number X 17 and forms compound PX, while Q combines with element with atomic number 8 Y and forms compound Q2Y. Find the atomicity and classify the compound PX and Q2Y.

The compound PX will be NaCl and Q2Y will be K2O.
- It is given that Sodium (P) combines with the element having atomic number 17 which is Chlorine. Sodium has a valency of +1, so it will donate one electron to Chlorine which has a valency of -1. Thus the compound NaCl will be formed. Its atomicity is 2.
- Next, Potassium (Q) combines with Oxygen (having atomic number 8) and forms K2O. Because the valency of oxygen is -2 and it will combine with 2 atoms of potassium (valency +1). The atomicity of K2O is 3.
