How would the size of the Cl atom compare to the size of Cl-1?
Understand the Problem
The question is asking about the comparison in size between a chlorine atom (Cl) and its anion (Cl-1). The approach to solve this includes discussing atomic size and the impact of gaining an electron on ion size.
Answer
Cl- is larger than Cl.
The final answer is that Cl- is larger than Cl.
Answer for screen readers
The final answer is that Cl- is larger than Cl.
More Information
When an atom gains an electron, electron-electron repulsion within the atom increases, causing the electrons to spread out more and increase the size of the ion.
Tips
Be careful not to confuse atomic radius with ionic radius; ions can have different sizes even within the same element due to electron gain or loss.
