Step 1: Write Electron Configurations

Electron configurations describe how electrons are arranged in an atom's energy levels.

Here are five elements with their configurations:

1. Hydrogen (H) → 1s¹
2. Oxygen (O) → 1s² 2s² 2p⁴
3. Sodium (Na) → 1s² 2s² 2p⁶ 3s¹
4. Chlorine (Cl) → 1s² 2s² 2p⁶ 3s² 3p⁵
5. Calcium (Ca) → 1s² 2s² 2p⁶ 3s² 3p⁶ 4s²

Step 2: Create Bohr and Lewis Dot Diagrams

Bohr Models (Energy Levels Representation)

• Hydrogen (H): 1 electron in the first shell.
• Oxygen (O): 2 electrons in the first shell, 6 in the second.
• Sodium (Na): 2 electrons in the first shell, 8 in the second, 1 in the third.
• Chlorine (Cl): 2 electrons in the first shell, 8 in the second, 7 in the third.
• Calcium (Ca): 2 electrons in the first shell, 8 in the second, 8 in the third, 2 in the fourth.

Lewis Dot Diagrams (Valence Electrons Representation)

• Hydrogen (H): H• (1 valence electron)
• Oxygen (O): •O•• (6 valence electrons)
• Sodium (Na): Na• (1 valence electron)
• Chlorine (Cl): •Cl•• (7 valence electrons)
• Calcium (Ca): Ca•• (2 valence electrons)

Step 3: Predict Bonding (Ionic or Covalent?)

• Ionic Bonds (between metals and nonmetals, involve electron transfer):
  • Sodium (Na) + Chlorine (Cl) → NaCl (Sodium donates its 1 electron, forming Na⁺ and Cl⁻).
  • Calcium (Ca) + Oxygen (O) → CaO (Calcium donates 2 electrons to oxygen).
• Covalent Bonds (between nonmetals, involve electron sharing):
  • Oxygen (O) + Hydrogen (H) → H₂O (Water, sharing electrons).
  • Chlorine (Cl) + Oxygen (O) → ClO₂ (Chlorine dioxide, sharing electrons).

Conclusion:

By analyzing electron configurations, Bohr models, and Lewis dot diagrams, we can predict how elements form ionic or covalent bonds, helping us understand chemical interactions! 🔬✨
