Question

1. on the same graph, make a line graph the first three atoms in group 2a listed below in a different color.

group 2a
element\tie (kj/mole)
be\t900
mg\t736
ca\t590
graph with y - axis labeled ionization energy (values 300, 600, 900, 1200, 1500, 1800, 2100) and x - axis labeled atomic number (values 1 to 20) in a grid format

Explanation:

Step1: Identify Atomic Numbers

Find atomic numbers of Be, Mg, Ca. Be (4), Mg (12), Ca (20).

Step2: Plot Points

For Be: (4, 900); Mg: (12, 736); Ca: (20, 590). Mark these on the graph (x - atomic number, y - ionization energy).

Step3: Draw Line

Connect the plotted points with a line, using a distinct color.

Answer:

To create the line graph:

1. Plot Points: Mark (4, 900) for Be, (12, 736) for Mg, and (20, 590) for Ca on the graph (x - atomic number, y - ionization energy).
2. Draw Line: Connect these points with a line (e.g., red) to represent Group 2A’s first three elements’ ionization energy trend.

(Note: The graph’s y - axis is ionization energy (kJ/mol), x - axis is atomic number. Ensure the line connects the three plotted coordinates clearly.)
