N203 is the answer, if i am wrong im sorry!
Answer: option <span>B. The nucleus contains protons and neutrons and is orbited by electrons.
This is the planetary model, which is so known nowadays, but it is not correct. The quantum model is based in orbitals (not orbits), which are regions around the nucleus where are the electrons, but they are not circling around the nucleus. </span>
<span>The electrons in the outer shell of Xenon are much further away from the nucleus than the electrons in the outer shell of Neon. The Xenon electrons are much less bound to the atom than Neon, and a strong electronegative atom like fluorine succeeds in tearing off an electron.</span>
Potassium chloride react with iodine(I) chloride to produce potassium dichloridoiodate(I) complex and it will be displacement reaction.
<h3>
What is Displacement Reaction ?</h3>
A single-displacement reaction, also known as single replacement reaction or exchange reaction, is a chemical reaction in which one element is replaced by another in a compound.
Therefore, Potassium chloride react with iodine(I) chloride to produce potassium dichloridoiodate(I) complex and it will be displacement reaction.
