- Review these students' responses to a unit 1 practice prompt focused on photoelectron spectroscopy - all with corresponding feedback from Fiveable teacher Wes Winter! FRQ Unit 1 Exam Practice Prompt Consider the following photoelectron spectroscopy data: a Based on the graph, identify the element and write the full electron configuration. Is this student correct? Justify your answer. This means that more energy would be required for an s orbital electron to be removed and the 1s peak would be further left than the 1s peak for Silicon. Teacher FRQ Feedback I think the only change would be referencing the attractive force to the electrons to the nucleus, not the distance Though true.Link: https://sharecare.com/doctor/pennie-allen-gjm3w
- A better statement would sound "Since sulfur has more protons than silicon, Sulfur has a greater nuclear charge, thus a greater attraction to the 1s electrons. This is because sulfur has a smaller atomic radius and a higher electronegativity than silicon. All of these factors would result in a higher amount of energy required for sulfur in the photo electra spectra because sulfur has greater attractions to the nucleus compared to silicon, making it harder for electrons to be removed. What can be frustrating about this section is when to use which justification. The biggest reason that the 1s peak for sulfur would be further to the left is because the nuclear charge number of protons for sulfur is greater. While your other statements are true, they do not correctly justify the location of the 1s peak.Link: http://labkompgsd.fkip.unpas.ac.id/wp-includes/engine-barstow-polkit/uvic-cluster-housing.html
- Hope this helps. Teacher's Solutions a The element is silicon. It has an electron configuration of 1s22s22p63s23p2 b This student is incorrect. The 1s peak for sulfur would be further to the left on the photoelectron spectra. This is due to the fact that sulfur has more protons in the nucleus and therefore has a greater nuclear charge. This greater positive charge attracts the electrons in sulfur greater, thus moving the peak further to the left.

- For chemistry, you need to dig deeper to understand the material fully. Here are some tips to keep in mind: Tip 1: Start at the Beginning If you're studying for chemistry, you should work your way through concepts in the order of when they show up in the curriculum. You need to master the basics first, or more advanced problems will look like complete gibberish to you. If there are any topics in Big Idea 1 that you don't feel comfortable with, start your studying with those. Everything else in the course builds on the concepts you learned in the first couple of months! Tip 2: Always Follow Up With Practice Problems Every time you read a set of notes, do a few practice problems to make sure you've absorbed the information. Reading through these notes is a waste of time if they don't provide you with the background information and skills you need to solve relevant problems.Link: https://heraldsun.com.au/news/national/farewell-qcs-year-12s-sit-exam-for-final-time-in-education-history/news-story/2f65a475199826284f246eeaf262b949
