Written by Gene Roddenberry and Arthur Heinemann (based on an original story by Roddenberry) and directed by Herschel Daugherty, it was first broadcast on March 7, 1969.
To do this, the nearest noble gas that precedes the element in question is written first, and then the electron configuration is continued from that point forward. For example, the electron notation of phosphorus is 1s 2 2s 2 2p 6 3s 2 3p 3, while the noble gas notation is [Ne] 3s 2 3p 3.
"Wink of an Eye" is the eleventh episode of the third season of the American science fiction television series Star Trek. Written by Arthur Heinemann, based on a story by Gene L. Coon (under the pen name Lee Cronin), and directed by Jud Taylor, it was first broadcast on November 29, 1968.
"The Cloud Minders" is the twenty-first episode of the third season of the American science fiction television series Star Trek. Written by Margaret Armen (based on a story by David Gerrold and Oliver Crawford) and directed by Jud Taylor, it was first broadcast on February 28, 1969.
Noble gas configuration is the electron configuration of noble gases. The basis of all chemical reactions is the tendency of chemical elements to acquire stability . Main-group atoms generally obey the octet rule , while transition metals generally obey the 18-electron rule .
This episode was released in Japan on December 21, 1993 as part of the complete season 3 LaserDisc set, Star Trek: Original Series log.3. [2] A trailer for this and the other episodes was also included, and the episode had English and Japanese audio tracks. [2] The cover script was スター・トレック TVサードシーズン [2]
The rule then predicts the electron configuration 1s 2 2s 2 2p 6 3s 2 3p 6 3d 9 4s 2, abbreviated [Ar] 3d 9 4s 2 where [Ar] denotes the configuration of argon, the preceding noble gas. However, the measured electron configuration of the copper atom is [Ar] 3d 10 4s 1. By filling the 3d subshell, copper can be in a lower energy state.
