The nuclear forces are considered as?

Correct answer: A. Strong force

  • A. Strong force
  • B. Weak force
  • C. Electromagnetic force
  • D. All of these options are correct

Explanation

Option A) Nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. They bind protons and neutrons ("nucleons") into the atomic nuclei. The nuclear force is about 10 million times stronger than the chemical binding that holds atoms together in molecules. It's 6 thousand trillion trillion trillion times stronger than the force of gravity. And that's because it binds the fundamental particles of matter together to form larger particles.Option B) Weak force is incorrect because the weak force is another fundamental force of nature that is responsible for certain types of radioactive decay, such as beta decay. It is much weaker than the strong force and does not play a significant role in holding the nucleus of an atom together.Option C) Electromagnetic force is incorrect because electromagnetic force is another fundamental force of nature that governs the interaction of electrically charged particles. It plays an important role in many physical phenomena, such as the behaviour of atoms and molecules, but it is not involved in holding the nucleus of an atom together.Option D) All of these options are correct is incorrect because only option A) Strong force is correct.

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.
