Which is most polarized noble gas?
1-Krypton
2-Xenon
3-Helium
4-Neon.
I think the one with the highest atomic number would be the most polarized one. Just a thought.
neon
xenon
To determine which noble gas is the most polarized, we need to consider the concepts of atomic size and electron-electron repulsion. As you suggested, the atomic number can provide some insight because noble gases generally increase in atomic size as you move down the periodic table.
However, atomic size alone is not the sole determining factor for polarity. To better understand the polarity of noble gases, we can examine their electron configuration.
Helium (He) has a stable electron configuration with 2 electrons that fully occupy the first energy level. Its small size and stable configuration make it the least polarizable noble gas.
Neon (Ne) has a similar configuration to helium, but its electron occupancy extends to the second energy level with 8 electrons. Neon's increased atomic size leads to higher polarizability compared to helium.
Moving down the periodic table, we find krypton (Kr) and xenon (Xe). Both have additional electrons occupying the third energy level compared to neon, making them larger and more polarizable.
Considering electron-electron repulsion, xenon (Xe) is more polarizable than krypton (Kr) due to its higher atomic number and larger size. Thus, out of the options provided, xenon (Xe) is the most polarized noble gas.
In summary, while atomic number and size are factors to consider when determining polarity, it is crucial to also examine electron configurations and electron-electron repulsion to make a definitive conclusion.
