How do you name an anion?

An ionic compound is named first by its cation and then by its anion. The cation has the same name as its element. For example, K+1 is called the potassium ion, just as K is called the potassium atom. The anion is named by taking the elemental name, removing the ending, and adding “-ide.”

Herein, what is an example of a monatomic ion?

A monatomic ion is an ion consisting of exactly one atom. If an ion contains more than one atom, even if these are of the same element, it is called a polyatomic ion. For example, calcium carbonate consists of the monatomic ion Ca2+ and the polyatomic ion CO32.

Which elements are Monatomic?

The noble gases exist as monatomic elements:
  • helium (He)
  • neon (Ne)
  • argon (Ar)
  • krypton (Kr)
  • xenon (Xe)
  • radon (Rn)
  • oganesson (Og)

What is the most stable monatomic ion formed from nitrogen?

Fluorine is a group 7A element. Neutral atom of Fluorine has 7 valence electrons. To acquire noble gas configuration it has only 1 less electron so it gains 1 electron and complete its valence shell and acquire stable configuration so the most stable mono atomic ion formed by Fluorine is F^-1.
