A Cation is a positive ion formed after removal of electron(s). For example, Fe^+2
The cation of lithium is Li+.
its positive
The ammonium ion, NH4+, is the only polyatomic cation.
Yes. Example of atomic cation is Na+. Example of atomic anion is Cl-. Example of molecular cation is NH4+. Example of molecular anion is NO3-.
For example the sodium cation, Na+.
For example the cation Bh7+.
No the fluoride ion is an anion
For example the sodium cation: Na+.
Mg^2+, Na^+. Any positively charged ion.
The only cation (positively charged ion) is ammonium NH4+ the others are all anions (negatively charged ions)
An example is calcium(11)oxide. Ca^2+ cation interact with O^2- anion
Well, a polyatomic may contain a cation in it. A cation is a positively charged ion. They are usually metals. A good way to remember is: "cats" have "paws" because they are "pawsitive". Cheesy, right? Anyways, an example of a polyatomic that contains a cation is NH4+. You know that this polyatomic has a cation by the +1 superscript. This + sign signifies a positive ion, which is called a cation!
