Multiple choice

What is the primary constituent of neutron star matter?

  1. Neutrons

  2. Protons

  3. Electrons

  4. Quarks
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Neutron stars are primarily composed of neutrons, which are subatomic particles with no electric charge. The intense gravitational forces within the star compress the matter to such an extent that protons and electrons combine to form neutrons.
