The Periodic Table of Videos has filmed at least one video for each of the 118 elements (from hydrogen to oganesson). [13] They have also filmed several videos that discuss molecules such as D 2 O (heavy water) [14] and sulfuric acid. [15] Also filmed are "Chem definitions" that provide an explanation to words that are used in chemistry.

The 2014 AP Chemistry exam was the first administration of a redesigned test as a result of a redesigning of the AP Chemistry course. The exam format is now different from the previous years, with 60 multiple choice questions (now with only four answer choices per question), 3 long free response questions, and 4 short free response questions.
The buildings on the Lake Ridge campus include Lower, Middle, and Upper School buildings, the Bettcher Convocation Center, which houses classrooms, a stage, and an auditorium, the Community Resource Center, a building holding four foreign language classrooms, three computer labs, a video lab, a Kiva gathering place, and a K–12 library.
An early example is CpFe(CO) 2 Si(CH 3) 3, prepared by silylation of CpFe(CO) 2 Na with trimethylsilyl chloride. Typical routes include oxidative addition of Si-H bonds to low-valent metals. Metal silyl complexes are intermediates in hydrosilation, a process used to make organosilicon compounds on both laboratory and commercial scales. [14] [15]
