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:

Step1: Recall sodium's properties

Sodium (Na) has atomic number 11. Its electron - configuration is 2, 8, 1. In the Bohr model, the nucleus contains 11 protons and 12 neutrons (average). There are 3 electron - shells: 2 electrons in the first shell, 8 in the second, and 1 in the third. For the Lewis structure, since it has 1 valence electron, the Lewis symbol is Na with a single dot.

Step2: Recall chlorine's properties

Chlorine (Cl) has atomic number 17. Its electron - configuration is 2, 8, 7. In the Bohr model, the nucleus contains 17 protons and 18 neutrons (average). There are 3 electron - shells: 2 electrons in the first shell, 8 in the second, and 7 in the third. For the Lewis structure, since it has 7 valence electrons, the Lewis symbol is Cl with 7 dots around it.

Answer:

Bohr model of sodium: Draw a small circle to represent the nucleus with "Na" inside. Around the nucleus, draw 3 concentric circles for electron - shells. Put 2 dots on the innermost circle, 8 dots on the second - circle, and 1 dot on the outermost circle.
Lewis structure of sodium: Draw "Na" with a single dot next to it.
Bohr model of chlorine: Draw a small circle to represent the nucleus with "Cl" inside. Around the nucleus, draw 3 concentric circles for electron - shells. Put 2 dots on the innermost circle, 8 dots on the second - circle, and 7 dots on the outermost circle.
Lewis structure of chlorine: Draw "Cl" with 7 dots around it.
