Nuclei
Understand the Problem
The question is asking about 'nuclei', which could pertain to various scientific fields like biology or physics. It requires further context to determine the specific aspect of nuclei being referenced, such as their structure, function, or role in a particular process.
Answer
Atomic nuclei consist of protons and neutrons and make up most of an atom's mass.
In the context of atomic nuclei, it consists of electrically positive protons and electrically neutral neutrons, held together by the strong force. These nuclei contain more than 99.9% of the atom's mass but occupy much less than 0.01% of its volume.

More Information
The nucleus is a tiny fraction of the atom's volume but contains nearly all its mass due to the presence of protons and neutrons. The strong nuclear force keeps these particles bound together, preventing them from being repelled by electromagnetic forces.
