While at Hamilton high school (2005), Morton Schmidt (Jonah Hill) was an honor roll geek and Greg Jenko (Channing Tatum) was a popular but underachieving jock. Seven years later, they both graduate from the Metropolitan City Police Academy and are partnered with each other. Because of their youthful looks and the fact that they forgot to read a suspect his Miranda rights, they are assigned to go undercover in a high school in order to infiltrate a drug ring and catch the supplier. Schmidt, under the name Brad McQuaid, is "enrolled" in advanced placement (AP) classes; while Jenko, as his brother Doug, is placed in the no-brainer classes. Unfortunately, they get their undercover names mixed up, and Schmidt attends the no-brainer classes while Jenko attends the AP classes.

21 Jump Street is based on the television series 21 Jump Street (1987). The story and screenplay were written by Jonah Hill and American screenwriter Michael Bacall. It is followed by 22 Jump Street (2014).

If anything, the film is a continuation of the series and works as a reboot of the franchise. Captain Hardy states that "21 Jump Street" was a project in the 1980s, the time of the series, and is being revived. Also, several actors reprise their characters.

Atoms are composed of a nucleus containing positively-charged protons and a shell in which negatively-charged electrons orbit around the nucleus, much like a sun and its planets. When two (or more) atoms bond with each other, they form a molecule. The difference between a covalent bond and an ionic bond is how the two atoms are linked to each other to form the molecule. In an ionic bond, the electron of one atom is transferred to the other atom, effectively making one atom positive (cation) and the other negative (anion), and positives are attracted to negatives, so the atoms "stick" to each other. In covalent bonding, both atoms share the same electron. This sharing of an electron also helps make two atoms stick together.
