- 87. Francium (Fr) has an atomic number of 87, meaning it has 87 protons and 87 electrons in its neutral state. It is named Francium as a tribute to France, the country in which it was discovered, according to LiveScience. It can be found on the lower-left corner of the periodic table. It has the lowest electronegativity of any element (I think) and one of the largest diameters. It's really radioactive however, and its most stable isotope has a half-life of only 22 minutes according to Wikipedia.
- 88. 88 is used as an anti-Semitic hate-symbol, according to the anti-defamation league. Never use it! Ever!
- 89. "89" is a documentary about the soccer (<- this is the American word for football) team Arsenal making history by defeating arsenal.
- 90. The 90s were a period in American popular culture lasting from 1990 to 1999. Defining fads of the decade include grunge music from bands such as Nirvana, overly detailed Nike sneakers, and cartoons from Nickelodeon/Cartoon Network/Disney such as Teenage Mutant Ninja Turtles, Ruggrats, and the Powerpuff Girls.
91 is the only number to use prime numbers that american culture has a superstition with which are 7 and 13
92. "LA 92" is a documentary about the days following the Rodney King trial in 1992.
93. "93" is a song by 6ix9ine as well as a number who is entirely made of multiples of three, making it divisible by 3. Specifically, it's 3*11, and 311 is an epic rock band popular during the... that's right... 90s!
