Question 27

When naming monoatomic and polyatomic ions, what does the prefix "hypo" mean?

Answer 27

There is less oxygen then normal "ite" endings, so we use hypo as a prefix. Examples: Hypochlorite, hypobromite, etc. in polyatomic ions that follow the following formula XO subscript Y

Question 28

When naming monoatomic and polyatomic ions, what does the prefix "per" mean?

Answer 28

More oxygen then normal. Examples: Perchlorite, Perbromite in polyatomic ions that follow the following formula XO subscript Y

Question 29

When naming monoatomic and polyatomic ions, what does the suffix "ide" mean?

Answer 29

A monoatomic ion with no oxygen and only one of that element (typically, exceptions exist) in polyatomic ions that follow the following formula XO subscript Y

Question 30

When naming monoatomic and polyatomic ions, what does the suffix "ite" mean?

Answer 30

More oxygen in polyatomic ions that follow the following formula XO subscript Y

Question 31

When naming monoatomic and polyatomic ions, what does the suffix "ate" mean?

Answer 31

More oxygen than the one with ite in polyatomic ions that follow the following formula XO subscript Y
