Explanation:
What kind of elements from positively charged ions?
Positive ions are cations and are typically metals like copper or sodium. Negatively-charged ions are anions, formed from nonmetallic elements like oxygen and sulfur.
What kind of elements from negatively charged ions?
Negatively-charged ions are anions, formed from nonmetallic elements like oxygen and sulfur.
Why sodium ion is not reactive, but Na metal is very reactive?
Sodium ion has eight electrons in its valency shell and it is the minimum state of energy while the sodium metal has one electron in valency shell so the sodium metal is very reactive.
