Kent McCorkle, or "Dr. Kent' to his student, has helped thousands of students be successful in chemistry. Unlike monoatomic ions, which are composed of a single atom, polyatomic ions are composed of many atoms. Depending on your course or instructor, you may need to memorize some of the following. When it comes to memorizing the, flashcards are your friends! The good news, is there are dozens of other polyatomic ions that are relatively easy to figure just by knowing or observing a few patterns. If you refer to the periodic table below, you will that a several nonmetals have been highlighted that commonly form such oxyanions.
A molecular ion is a covalently bonded set of two or more atoms, or of a metal complex , that can be considered to behave as a single unit and that has a net charge that is not zero. Unlike a molecule , which has a net charge of zero, this chemical species is an ion. The prefix poly- carries the meaning "many" in Greek, but even ions of two atoms are commonly described as polyatomic. In older literature, a polyatomic ion may instead be referred to as a radical or less commonly, as a radical group. In contemporary usage, the term radical refers to various free radicals , which are species that have an unpaired electron and need not be charged. Polyatomic ions often are useful in the context of acid-base chemistry and in the formation of salts.

Беккер в очередной раз послал бармену проклятие за коктейль, выбивший его из колеи. Это был один из старых потрепанных севильских автобусов, и первая передача включилась не. Расстояние между Беккером и ним сокращалось. Нужно было во что бы то ни стало догнать его, пока не включилась следующая передача. Сдвоенная труба глушителя выбросила очередное густое облако, перед тем как водитель включил вторую передачу. Беккер увеличил скорость. Поравнявшись с задним бампером, он взял немного правее.
