A monatomic ion is an ion consisting of one or more atoms of a single element (unlike a polyatomic ion, which consists of more than one element in one ion). A type Ibinary ionic compound contains a metal (cation) that forms only one type of ion. A type II ionic compound contains a metal that forms more than one type of ion, i.e., ions with different charges.
anion , atom or group of atoms carrying a negative charge. The charge results because there are more electrons than protons in the anion. Anions can be formed from nonmetals by reduction (see oxidation and reduction ) or from neutral acids (see acids and bases ) or polar compounds by ionization. Anionic species include Cl - , SO 4-- , and CH 3 COO - . Highly colored intermediates in organic reactions are often radical anions (anions containing an unpaired electron). Salts are made up of anions and cations . See ion .
cation , atom or group of atoms carrying a positive charge. The charge results because there are more protons than electrons in the cation. Cations can be formed from a metal by oxidation (see oxidation and reduction ), from a neutral base (see acids and bases ) by protonation, or from a polar compound by ionization. Cationic species include Na + , Mg ++ , and NH 4+ . The cations of the transition elements have characteristic colors in water solution. Salts are made up of cations and anions . See ion .

Answers:First of all, Flourine and Lithium are not both alkali earth metals. lithium's an alkali metal and flourine's a halogen; these names are derived from the columns in which they're found on the periodic table (the first column on the left for lithium and the second column from the right for flourine). Ionization has to do with the arrangement of electrons around the nucleus. There's things called electron shells, each can house a certain number of electrons. the outermost shell is called the valence shell. Atoms want to be stable, which basically means that their valence shell is full. It takes eight electrons in the outermost shell to stabilize. The reason that certain elements gain and certain elements lose depends on their position on the periodic table. Lithium and sodium are in the first column, and all of these have one electron in their valence shell. Rather than try and scrounge up seven electrons to fill that shell up, they drop the spare one and the next shell down is full, so they're stable. This is why they get positive charges; when they lose that electron there's more protons than electrons. The opposite is true of Flourine, Chlorine, etc in the seventh period (second column from the right). These have seven electrons in their valence shells, so it's easier for them to gain one to be stable. Incidentally, you'll notice that this is why atoms like Sodium and Chlorine pair up so well in ionic compounds; the sodium wants to get rid of an electron and the chlorine wants to gain an electron, so they're a perfect match! Finally, you'll never find lithium and sodium paired up in an ionic compound. each of the ions separately has a charge of 1+, however, because of the conditions mentioned above. Hope this helps a little bit!
Answers:if an atom LOSES an electron it means that a negative charge is being withdrawn from the ion..thus it becomes more positive..if the charge of the resulting ion is positive it is called a CATION. on the other hand, if an ion GAINS an electron..it means that the ion becomes more negative since it induces a negative charge (electron is negative) thus making the charge of the ion also negative..this is now called the ANION :D
Answers:A cation, is any ion that has a positive charge. While an anion, is any ion that has a negative charge. That's the basic idea. Good luck!
