Atomic radius of hydrogen is 37pm. Express it in metres. And explain h

1.	Atomic radius of hydrogen is 37pm. Express it in metres. And explain how does atomic size vary in a group & in a period.
Answer» Answer: 37×10^-12m Explanation: 1pm = 10^-12 m 37pm= 37×10^-12m down a group , ATOMIC size increases due to DECREASE in effective nuclear CHARGE. along a period from left to right , atomic size decreases due to increase in effective nuclear charge

Atomic radius of hydrogen is 37pm. Express it in metres. And explain how does atomic size vary in a group & in a period.

Answer»

Answer:

37×10^-12m

Explanation:

1pm = 10^-12 m

37pm= 37×10^-12m

down a group , ATOMIC size increases due to DECREASE in effective nuclear CHARGE.

along a period from left to right , atomic size decreases due to increase in effective nuclear charge
