Hey are you Udgamite? If yes then please rate my answer as 4 star and thank my answer
Answer:
The increasing order is P,Q and R.
Explanation:
Since atomic size generally decreases along a period, as the atomic number (nuclear charge) increases thus, the element with smaller radii, has the highest atomic number. Hence, Q has the highest atomic number followed by R and P.
