Question

in atoms, electrons surround the nucleus in
a random patterns.
b specific energy levels.
c orbits like the planets.
d a \plum pudding\ type of arrangement

Explanation:

In an atom, electrons are arranged in specific energy levels (also known as electron shells). This is a fundamental concept in atomic structure. Electrons do not orbit like planets (this was a model in early atomic theory but is not accurate). They are not in random patterns. The "plum - pudding" model (where electrons are embedded in a positively - charged 'pudding') was also an early and incorrect model.

Answer:

B. specific energy levels
