QuestionAnatomy and Physiology
For each atom in the table below, write down the subshell from which an electron would have to be removed to make a + 1 cation, and the subshell to which an electron would have to be added to make a - 1 anion.
The first row has been completed for you.
| atom | subshell from which electron removed to form + 1 cation | subshell to which electron added to form - 1 anion |
| --- | --- | --- |
| H | 1s | 1s |
| Hg | | |
| Ne | | |
| K | | |

Step 1: To make a + 1 cation, we need to remove an electron from the outermost shell.
"Hg (+1) cation" \Rightarrow "remove 1 electron from 6s subshell"
For Hg, the outermost shell is the 6s subshell.
Step 2: To make a - 1 anion, we need to add an electron to the outermost shell.
"Hg (-1) anion" \Rightarrow "add 1 electron to 6s subshell"
For Hg, the outermost shell is the 6s subshell.
Final Answer
| atom | subshell from which electron removed to form + 1 cation | subshell to which electron added to form - 1 anion | | --- | --- | --- | | H | 1s | 1s | | Hg | 6s | 6s | | Ne | 2p | 2s | | K | 4s | 4s | Note: The subshells for forming cations and anions are based on the electron configuration of the neutral atoms. The actual electron configuration of the ions may differ due to the rearrangement of electrons to achieve stability.
