To classify each atom based on whether it would gain or lose electrons to fulfill the octet rule, we need to analyze the electron configurations and the positions of the atoms in the periodic table.

1. **An atom in the halogen family**:
   - Halogens (Group 17) have 7 valence electrons. They need to gain 1 electron to achieve a full octet.
   - **Classification**: Gain electrons $$ \square $$

2. **A calcium atom**:
   - Calcium (Ca) is in Group 2 and has 2 valence electrons. It tends to lose these 2 electrons to achieve a stable electron configuration (similar to noble gases).
   - **Classification**: Lose electrons $$ \square $$

3. **An atom with an electron configuration of $$ [\mathrm{Xe}] 6 \mathrm{s}^{2} $$**:
   - This configuration corresponds to a Group 2 element (specifically, Radium, Ra). It has 2 valence electrons and will lose them to achieve a full octet.
   - **Classification**: Lose electrons $$ \square $$

4. **An atom with an electron configuration of $$ [\mathrm{Ar}] 4 s^{2} 3 d^{10} 4 p^{4} $$**:
   - This configuration corresponds to an element in Group 16 (specifically, Selenium, Se). It has 6 valence electrons and needs to gain 2 electrons to complete its octet.
   - **Classification**: Gain electrons $$ \square $$

### Summary:
- Gain electrons: 
  - An atom in the halogen family $$ \square $$
  - An atom with an electron configuration of $$ [\mathrm{Ar}] 4 s^{2} 3 d^{10} 4 p^{4} $$ $$ \square $$

- Lose electrons: 
  - A calcium atom $$ \square $$
  - An atom with an electron configuration of $$ [\mathrm{Xe}] 6 \mathrm{s}^{2} $$ $$ \square $$
- **Gain electrons**: - Halogen family $$ \square $$ - $$ [\mathrm{Ar}] 4 s^{2} 3 d^{10} 4 p^{4} $$ $$ \square $$ - **Lose electrons**: - Calcium atom $$ \square $$ - $$ [\mathrm{Xe}] 6 \mathrm{s}^{2} $$ $$ \square $$
