Question

d. what do you observe when you lower the voltage to around 20 volts? explain why. spectral lines become less intense and fewer types of transitions may occur due to less electron excitation

1. run the simulation using hydrogen for a few seconds. then switch to sodium.

a. what do you notice about the spacing of the electron levels of these two elements? hydrogen has more evenly spaced electron levels compared to sodium more complex and irregular spacing
b. as the sodium simulation runs, what do you notice about the number of transitions in the uv, visible and far ir portions of the spectrum? explain your observations, referring to your answer to 3a and comparing its spectrum to that of hydrogen.
analysis questions:

1. how did the electrons in the elements you observed become “excited”? gases - absorb energy heat,electrical and discharge

Explanation:

a. Hydrogen has more evenly - spaced electron levels due to its simpler atomic structure compared to sodium's more complex and irregularly - spaced levels.
b. Sodium likely has more transitions in different spectral regions (UV, visible, far - IR) because its more complex electron - level structure allows for a greater variety of electron transitions compared to hydrogen. When the voltage is lowered to around 20 volts, fewer electrons are excited, resulting in less intense spectral lines and fewer types of transitions. Electrons in the observed elements become excited when the gas absorbs energy in the form of heat or electrical discharge.
d. When the voltage is lowered to around 20 volts, the spectral lines become less intense and fewer types of transitions occur because there is less electron excitation.

Answer:

a. Hydrogen has more evenly spaced electron levels compared to sodium's more complex and irregular spacing.
b. Sodium likely has more transitions in different spectral regions compared to hydrogen due to its more complex electron - level structure.
d. Spectral lines become less intense and fewer types of transitions occur due to less electron excitation.
