Question

9. Which of the colors of light has the highest energy? Which has the lowest frequency? Which has the longest wavelength? The periodic Table 10. The Modern Periodic Law states that properties of elements occur in a repeating pattern when arranged according to increasing 11. Elements located in Groups 1A-8A (1-2,13-18) on the periodic table are referred to as elements. 12. Name an inner transition element Name a transition element in the 4th, period 13. In period 2, which element has the least metallic character? In group VA, which element has the greatest metallic character? 14. Name one element with similar properties to Lithium? How many valence electrons do those elements have? 15. Of the alkaline earth metals, which element has the smallest atomic radius? Which element has the largest atomic radius? 16. Write the electron dot formula for: a. Phosphorus b. Sodium 17. What is the electron configuration of Co? What is the electron configuration of F? 18. Of the halogens, which element has the highest ionization energy?

Explanation / Answer

9) a. Of visible light, violet has the most energy and red the least

b. It's red! The wavelengths of the other colors decrease in order, with violet light having the shortest. In this hands on lab, you will construct a simplified model of different light waves in order to determine a constant relationship between wavelength and frequency.

c. The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light

10) Atomic Number

11) Main Group Element

12) a. lanthanum and b. Titanium

13) a. Neon and b. Bismuth

14) a. Magnesium and

b. the electron configuration of Mg is 1s
