Students are tasked with analyzing various PES plots to identify atomic sublevels, determine the number of valence electrons, and deduce the identity of the represented elements. The worksheet further includes comparative analysis of aluminum and magnesium, requiring students to label energy peaks, identify ionization energy points, and explain periodic trends such as the differences in first ionization energy based on electron configuration and proton count. Designed as a study aid for chemistry students, the material facilitates mastery of electronic structure concepts, subshell energy levels, and periodic properties. By examining ground-state spectra, learners develop critical skills in evaluating atomic data and relating physical measurements to theoretical orbital energy representations.",{"@graph":14,"@context":72},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/exam/","Exam",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/pes-practice-photoelectron-spectroscopy-analysis/665565/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/pes-practice-photoelectron-spectroscopy-analysis/665565.png","ImageObject",300,407,{"name":42,"@type":43},"Guten Appetit_Joghurt","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-10-29",true,{"@type":52,"interactionType":53,"userInteractionCount":33},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"What is the primary objective of analyzing the PES spectra in this document?","Question",{"text":62,"@type":63},"The objective is to identify the electron configuration and element for each provided spectrum by labeling sublevels and determining the number of valence electrons.","Answer",{"name":65,"@type":60,"acceptedAnswer":66},"Why does aluminum exhibit a lower first ionization energy than magnesium?",{"text":67,"@type":63},"Aluminum has a lower first ionization energy because its outermost electron occupies a 3p subshell, which is higher in energy and further from the nucleus than the 3s subshell occupied by magnesium's valence electrons.",{"name":69,"@type":60,"acceptedAnswer":70},"How do you identify the first electron to be removed from an atom in a PES spectrum?",{"text":71,"@type":63},"The first electron to be removed corresponds to the peak with the lowest binding energy, which is located furthest to the right on a standard PES graph.","https://schema.org",{"og:url":32,"og:type":74,"og:title":10,"og:site_name":45,"og:description":12},"article",{"robots":76,"canonical":32},"index,follow",{"doc_id":78,"site_id":7},665565,1793304986,{"code":4,"msg":81,"data":82},"success",[83,87,91,94,99,104,109,114,119,122,126],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":84,"show_sort_weight":85,"slug":86},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":88,"show_sort_weight":89,"slug":90},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":92,"slug":93},70,"exam",{"id":95,"doc_module":4,"doc_module_name":25,"category_name":96,"show_sort_weight":97,"slug":98},5,"Comic",60,"comic",{"id":100,"doc_module":4,"doc_module_name":25,"category_name":101,"show_sort_weight":102,"slug":103},6,"Technology",50,"technology",{"id":105,"doc_module":4,"doc_module_name":25,"category_name":106,"show_sort_weight":107,"slug":108},7,"Healthcare",40,"healthcare",{"id":110,"doc_module":4,"doc_module_name":25,"category_name":111,"show_sort_weight":112,"slug":113},8,"Research & Report",30,"research-report",{"id":115,"doc_module":4,"doc_module_name":25,"category_name":116,"show_sort_weight":117,"slug":118},9,"Religion & Spirituality",20,"religion-spirituality",{"id":117,"doc_module":4,"doc_module_name":25,"category_name":120,"show_sort_weight":117,"slug":121},"World Cup","world-cup",{"id":123,"doc_module":4,"doc_module_name":25,"category_name":124,"show_sort_weight":123,"slug":125},10,"Lifestyle","lifestyle",{"id":127,"doc_module":4,"doc_module_name":25,"category_name":128,"show_sort_weight":95,"slug":129},19,"General","general",{"code":4,"msg":81,"data":131},{"doc_id":78,"user_id":132,"nickname":42,"user_avatar":133,"doc_module":4,"category_id":33,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":33,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":33,"language":139,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":12,"update_tm":79,"read_time":123},1374408768420,"https://ap-avatar.wpscdn.com/davatar_6f874abed73319feea01a86fa6f0fab8","PES Practice Name:   Date:  Block:   \nDirections: Each PES spectrum below represents an atom in its ground state.
