Draw a bar graph showing the number of electrons in each energy level for any three elements.
To draw the bar graph, we first select three elements and note their electron distribution from Table 8.4. Let us choose Hydrogen (K=1, L=0, M=0), Carbon (K=2, L=4, M=0), and Sodium (K=2, L=8, M=1).
On the graph, the X-axis represents the energy levels (K, L, M), and the Y-axis represents the number of electrons. For Hydrogen, draw a bar of height 1 at the K-shell. For Carbon, draw a bar of height 2 at the K-shell and height 4 at the L-shell. For Sodium, draw bars of height 2 at the K-shell, height 8 at the L-shell, and height 1 at the M-shell. The bars for each element should be grouped or color-coded for clarity.
Explanation
The question requires representing electron distribution data visually. Since a visual graph cannot be drawn in text, the answer provides the exact data and instructions for constructing the bar graph. The elements chosen (Hydrogen, Carbon, and Sodium) effectively demonstrate how electrons fill the K, L, and M shells progressively, as outlined by the Bohr and Bury rules and Table 8.4 in the textbook.
Solution Steps
Step 1: Select three elements (e.g., Hydrogen, Carbon, Sodium) and identify their electron distribution in K, L, and M shells from Table 8.4.
Step 2: Label the X-axis with the energy levels (K, L, M) and the Y-axis with the number of electrons.
Step 3: For each element, draw bars at the respective energy levels with heights corresponding to the number of electrons in that shell.
