One up quark and 2 down quarks. when Combine, make a:
Correct answer: A. Neutron
- A. Neutron
- B. Proton
- C. Electron
- D. Positron
Explanation
When one up quark and two down quarks combine, they form a neutron. Neutrons are subatomic particles that are found in the nucleus of atoms. They have no electric charge and are slightly heavier than protons. Neutrons play a crucial role in the stability of atomic nuclei.

About Composition of Atomic Nuclei
Atomic nuclei contain positively charged protons and electrically neutral neutrons, collectively called nucleons. Questions use atomic number, mass number and nuclear notation to identify isotopes, isobars and isotones, and may connect nuclear composition with nuclear charge, mass defect, binding energy and the stability of the nucleus.
