Explicación
1. Calcium is in Group 2 of the periodic table, which means it has 2 valence electrons. Therefore, its Lewis dot diagram would have 2 dots around it.2. Carbon is in Group 14 of the periodic table, which means it has 4 valence electrons. Therefore, its Lewis dot diagram would have 4 dots around it.3. Iron is in Group 8 of the periodic table, which means it has 2 valence electrons. Therefore, its Lewis dot diagram would have 2 dots around it.4. Hydrogen is in Group 1 of the periodic table, which means it has 1 valence electron. Therefore, its Lewis dot diagram would have 1 dot around it.5. Helium is in Group 18 of the periodic table, which means it has 2 valence electrons. Therefore, its Lewis dot diagram would have 2 dots around it.6. Aluminum is in Group 13 of the periodic table, which means it has 3 valence electrons. Therefore, its Lewis dot diagram would have 3 dots around it.7. Chlorine is in Group 17 of the periodic table, which means it has 7 valence electrons. Therefore, its Lewis dot diagram would have 7 dots around it.8. Argon is in Group 18 of the periodic table, which means it has 8 valence electrons. Therefore, its Lewis dot diagram would have 8 dots around it.
