Answer 2

Answer:

The correct answer is option B

Explanation:

• X-ray or other spectroscopy techniques are used to calculate the atomic radius of an atom. The periodic table displays the atomic radii of elements in a predictable pattern. By taking into account the nuclear charge and energy level, we can explain this trend.
• In general, the atomic radius increases when we move down a group and decreases as we move from left to right in a period. The valence electrons are in the same outermost shell during periods, which explains this. Moving from left to right, the atomic number rises over the same time interval, increasing the effective nuclear charge. Elemental atomic radius decreases as attractive forces increase.
• Chlorine has a proton number of 17. By writing out the subshell notation, we know that chlorine atom has 7 electrons in the outermost shell.
• Chlorine anion, or chloride ion, on the other hand, since it has accepted 1 electron to achieve stable octet arrangement, it has 8 electrons in the outermost shell.
• The proton number of both chlorine and chloride ion does not change, but remains at 17. Hence, we can deduce that the forces of attraction exerted on the outermost electron in chloride ion is lesser than chlorine atom, since there are more electrons.
• Conclusion, chloride ion has a bigger atomic radius due to an increase in number of electrons.
