Strong nuclear force. I think that's the one one that holds the nucleons together.
Explanation:
element x _ carbon having two shells 2,3
element y _ fluorine atomic no 9 EC 2,7
when carbon react with fluorine it destroyes graphite and form fluorocarbons and thus form covalent bond
hope it helps u

Answer:
D. The behavior of an atom's electrons can be described by circular orbits around a nucleus.
Explanation:
<em>Which of the following statements is INCORRECT? </em>
<em>A. It is not possible to know the exact location of an electron and its exact energy simultaneously.</em> CORRECT. This is known as the Heisenberg's uncertainty principle.
<em>B. The energies of an hydrogen atom's electrons are quantized.</em> CORRECT. According to the modern atomic model, the energy levels are quantized, that is, they have a discrete amount of energy.
<em>C. The wave mechanical model correctly predicts all the energy states and the orbitals available to an electron in an hydrogen atom.</em> CORRECT. The characteristics of the energy levels are explained by Schrödinger's wave equation.
<em>D. The behavior of an atom's electrons can be described by circular orbits around a nucleus.</em> INCORRECT. This was postulated by Bohr's atomic model but it is now considered to be incorrect.
<em>E. Electrons have both wave and particle properties.</em> CORRECT. This is what De Broglie called wave-particle duality.
The best and most correct answer among the choices provided by your question is the fourth choice or letter D.
Carbon is responsible for the variety of carbon-based molecules on Earth because it is organic in nature.
