Question

1. draw a bohr model for sodium (na). sodium has three energy levels and eleven electrons. once complete, upload for your teacher to grade.

Explanation:

Step1: Draw the nucleus

Draw a small circle to represent the nucleus of sodium. Write "11p + 12n" inside it (11 protons and 12 neutrons, as sodium - 23 has atomic number 11 and mass number 23).

Step2: Fill the first energy level

The first energy level (K - shell) can hold a maximum of 2 electrons. Draw a circle around the nucleus and place 2 dots (representing electrons) on it.

Step3: Fill the second energy level

The second energy level (L - shell) can hold a maximum of 8 electrons. Draw a larger circle around the first - level circle and place 8 dots on it.

Step4: Fill the third energy level

The remaining 1 electron (since 11-(2 + 8)=1) goes in the third energy level (M - shell). Draw an even larger circle around the second - level circle and place 1 dot on it.

Answer:

A correctly drawn Bohr model of sodium with a nucleus containing 11 protons and 12 neutrons, 2 electrons in the first energy level, 8 electrons in the second energy level, and 1 electron in the third energy level.
