You can't have a metal alkoxide. Well, you can, but you can't.
Ethanol is an alcohol, and has CH3CH2OH. If a reactive metal such as cesium is mixed with it, the hydroxide ion breaks to form hydrogen gas.
2CH3CH2OH (l) + Cs (s) --> CH3CH2O- (aq) + Cs+ (aq) + H2 (g)
Alkoxide is the conjugate base of the alcohol, hence CH3CH2O-

Metal alkoxides is then the hydrogen of the hydroxide group of an alcohol is replaced by a metal.
The most comon ones are sodium alkoxides as shown below.
CH3H2OH + NaH ->>> CH3CH2O-Na+ + H2.
Some metal alkoxides depending on the nature of the whole molecule can be very stable in nature.

An alkoxide is the conjugate base of an alcohol, and therefore has an organic group bonded to a negatively charged oxygen atom. They are generally basic. Alkoxides, though generally not stable, are found as intermediaries in various reactions, including the Williamson ether synthesis reaction for forming ethers. Often alkoxides and sulfonates have more than one beta-carbon bearing a proton for base abstraction in E2. Favoring one proton for removal over others (regioselectivity) can be accomplished by choice of base.

Alkoxides are the anions released on the breaking of the O-H bond in alcohols. When Metal ions (+ve) pair up with these alkoxides, metal alkoxides are formed.
