Question

The diagram shows four different locations in an atom. A shaded circle is shown, labeled nucleus. Two small points labeled one and three are shown inside this shaded circle. A lighter shaded concentric circle is shown with a radius more than double of the inner circle. A point labeled two is shown inside a section of this circle which does not overlap with the inner circle. A flower petal like shaded region is shown above and below these circles. A point labeled four is shown inside the lower petal. Which locations are likely to have subatomic particles that are constantly in motion?

Answer 1

Answer : 2

Explanation :

The shaded area labeled as 2 is likely to have subatomic particle that are constantly in motion.

The subatomic particles of the atom that are constantly in motion are called as electrons. The probability of finding electrons in the region shaded and labeled as 2. Electrons are in continuous motion in orbits around the nucleus of the atom. Therefore, the answer is 2.
