Answer:
The circumference of the bromine atom is 628 pm
Explanation:
The formula for the circumference of a circle is 2πr.
Where π is 3.14 and r is the radius of the circle.
Since atoms have a circular shape. The formula above can be used to determine the circumference of an atom (bromine atom in particular).
circumference of the bromine atom is 2πr (where r is 100 pm)
2 × 3.14 × 100 = 628 pm.
The circumference of the bromine atom is 628 pm
