Question

1. draw the bohr model for sodium (na) and then draw the lewis structure. 65. draw the bohr model for chlorine (cl) and then draw the lewis structure.

Explanation:

1. Bohr model of sodium (Na): Sodium has atomic number 11. In the Bohr - model, the first shell (K - shell) can hold 2 electrons, the second shell (L - shell) can hold 8 electrons, and the remaining 1 electron is in the third shell (M - shell). So, draw a nucleus labeled 'Na', with 11 protons and 12 neutrons (approximate mass number 23). Then draw 3 concentric circles representing the shells. Put 2 electrons in the innermost circle, 8 in the second - circle, and 1 in the outermost circle.
2. Lewis structure of sodium: Sodium is a metal in Group 1 of the periodic table. Its Lewis structure consists of the symbol 'Na' with 1 dot representing its valence electron.
3. Bohr model of chlorine (Cl): Chlorine has atomic number 17. In the Bohr - model, the first shell has 2 electrons, the second shell has 8 electrons, and the third shell has 7 electrons. Draw a nucleus labeled 'Cl', with 17 protons and 18 neutrons (approximate mass number 35). Then draw 3 concentric circles and put 2 electrons in the innermost circle, 8 in the second - circle, and 7 in the outermost circle.
4. Lewis structure of chlorine: Chlorine is in Group 17. Its Lewis structure consists of the symbol 'Cl' with 7 dots around it, representing its 7 valence electrons.

Answer:

• For sodium (Na):
• Bohr model: Draw a nucleus labeled 'Na' with 11 protons and 12 neutrons, 3 concentric circles with 2, 8, 1 electrons respectively.
• Lewis structure: 'Na' with 1 dot.
• For chlorine (Cl):
• Bohr model: Draw a nucleus labeled 'Cl' with 17 protons and 18 neutrons, 3 concentric circles with 2, 8, 7 electrons respectively.
• Lewis structure: 'Cl' with 7 dots.
