What are polyatomic ions * Your answer?
Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.
Why do I have to memorize polyatomic ions?
Polyatomic ions are important in chemistry because they are found in many common chemical compounds. Because of this, it is helpful to memorize the most common of these ions. Some teachers do allow students to use a list of polyatomic ions for exams while others do not.
How do you memorize polyatomic ions Reddit?
Use flashcards and write the information in blue ink. Then just sit down and start quizzing yourself. There’s some patterns in the naming but past that you just gotta straight up memorize them. Consider flashcards, repeatedly writing name/structure/formula, practice problems.
Why do we have to memorize polyatomic ions?
How do you name Polyatomics?
The naming of ionic compounds that contain polyatomic ions follows the same rules as the naming for other ionic compounds: simply combine the name of the cation and the name of the anion.
Why do I need to memorize polyatomic ions?
How do you memorize polyatomic charges?
Mnemonic Devices Use a mnemonic device to help remember the charges. For example, Mr. P of Papa Podcasts developed the phrase “Nick the Camel ate a Clam for Supper in Phoenix” to remember the polyatomic ions that end in “-ate.” The “-ate” is indicated in the sentence itself for easy memory.
Do I need to memorize polyatomic ions for AP Chem?

How do you write the names of polyatomic ions?
The cation is written first in the name; the anion is written second in the name. Rule 2. When the formula unit contains two or more of the same polyatomic ion, that ion is written in parentheses with the subscript written outside the parentheses.
Why does nitrate end in ate?
The -ate ending indicates a high oxidation state. The NO3- ion, for example, is the nitrate ion. The prefix hypo- is used to indicate the very lowest oxidation state. The ClO- ion, for example, is the hypochlorite ion.
