Which energy level is the closest to the nucleus?
Understand the Problem
The question is asking about the structure of an atom and specifically which energy level, or electron shell, is closest to the nucleus. In atomic physics, electrons occupy different energy levels, and the one closest to the nucleus is of particular interest.
Answer
The first energy level
The first energy level is closest to the nucleus.
Answer for screen readers
The first energy level is closest to the nucleus.
More Information
The first energy level, also known as the K-shell or 1-shell, is nearest to the nucleus. It has the lowest energy and can hold a maximum of 2 electrons.
Tips
Make sure to distinguish between different terminologies like 'K-shell' and '1-shell', as they refer to the same energy level.
