I need to get the names of these chemical formulas. btw, the numbers are suppose to be subscripts.
MgCl2----------Magnesium Chloride
Ag3P------------Silver Phosphoride
AlP---------------Aluminum Phosphoride
theres those other name endings like these: -ate, ide, ite, um.
when do i know which ending to use? btw, are my answers correct so far?

Magnesium chloride is correct, but it is silver phosphide and aluminum phosphide. You will use the ite and ate endings when you are naming compounds containing polyatomic ions. (NO3 - nitrate, NO2 - nitrite) When naming binary ionic compounds you use the name of the first element, the root of the second element plus ide.

The names you stated are correct, except for the last two. In the last part of those names the spelling is wrong. It should be spelled as Phosphide, not Phosphoride, therefore "Silver Phosphoride" becomes Sliver Phosphide and "Aluminum Phosphoride" becomes Aluminum Phosphide.
In answering your question on, "how to know when to use what ending", it is not a simple question to answer. You would need to know things like what a polyatomic ion is, how to recognize one in the chemical formula, and recognize one in the chemical name itself. A Polyatomic ion is a group of atoms that have acquired a charge. The names of Polyatomic ions usually end in ate, such as ClO3- (Chlorate). When they contain one less oxygen then they end ite, ClO2-(Chlorite). An exception to that is the hydroxide ion(OH-) and the Cyanide ion (CN-), which end in ide
*Note the - sign after the ion means a -1 charge.

You ask WAAY too much about lithium compounds. Sounds like you are trying to get a recipe for Crystal Meth and get answers to your homework at the same time. The PROBLEM with modern chemists, scientists, etc. is that they don't 'think' No wonder we can't figure out a more advanced way to fuel vehicles, lazy bums like you waltz through college expecting a handout all the tijme. Gimme money, gimme answers, heck do my term papers while you're at it also ... Guys like you make me sick. Get off your lazy rear and find a solution on you own, without partying with a bunch of frat losers for 3 straight weeks and then stressing over WHY you can't get this done ... College isn't a 4 year beer party, you know, it is a TIME and PLACE of LEARNING (Who'd have thunk it?). If you are still in high-school, then just wake the ^&*( up, and do your own danged homework like 'trance' said ... Vote for me, I want 10 points. (Hey if you can get a handout for everything, why can't I?) - don't be a SlacKeR ...

Your answers are correct. Ag3P is silver phosphide. AlP is aluminum phosphide. You must have a textbook or study guide. Come back here often. Also come to TheChemistryCluster in Yahoo! Groups. There are hundreds of experts who will answer questions there also.

the suffixes -ate and -ite usually come after chemicals withe oxygen in them...and -um is generally used for a few metals...-ide is usually used for ions!
did that help any?

I don't think there is anything as Phosphoride.
The correct word is Phosphide.
