Two chemistry questions

1. which group of elements will not form monatomic ions?

2. what type of elements form poly atomic ions?

1. Noble gases.

2. Nonmetals, some transition metals.

Explanation:

Hello,

Both questions aim the same, nonetheless, noble gases never form neither mono and polyatomic ions, nonmetals tend form both polyatomic ions and monoatomic ions, for instance, chlorine, could be chloride (monoatomic) and hypoclorite (), chlorite(), chlorate() and perchorate ().

Metals tend to form monoatomic ions, , etc by losing electrons in their upper shell.

There are some transition metals, such as chromium which could form both mono and polyatomic ions.

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
