Nickel-metal hydride batteries are a type of rechargeable battery with an electrochemistry similar to nickel cadmium batteries, but the eliminate the toxic cadmium metal.
The older nickel cadmium battery uses nickel oxide hydroxide and metallic cadmium as electrodes, while the newer nickel-metal hydride battery keeps the nickel oxide hydroxide electrode it uses a complex alloy that readily absorbs hydrogen atoms forming a metal hydride, it is the absorbed hydrogen within this hydride that actually functions as the active electrode in the battery. In addition to eliminating the toxic cadmium (making recycling or disposal easier and cheaper) this change also provides other advantages: higher battery capacity, no memory effect, etc.
Some of the different alloys used in the metal hydride electrode are:
- titanium nickel
- lanthanum neodymium nickel cobalt silicon
- cerium lanthanum neodymium praseodymium nickel cobalt silicon

Which would be a better drying agent between calcium hydride and strontium hydride?
calcium hydride
What is the chemical compound SnH2?
The compound SnH2 would be called either tin(II) hydride or stannous(II) hydride, but I'm not sure such a compound exists. The more common hydride of tin is tin(IV) hydride which is H2Sn, or SnH2.
What is the name of this compound NaH?
sodium hydride
What is the formula for phosophoros hydride?
Phosphorous Hydride = PH3
What is the formula of the hydride formed by sulfur?

What is the state of matter calcium hydride is in?
Calcium Hydride is a solid.
Is potassium hydride a transition metal?
No- it is an alkali metal hydride.
Is NAH a covalent hydride?
No this is an ionic hydride, with Na+ and H-

Sodium hydride is an ionic compound.
Does hydrogen and polonium make hydride?
The polonium hydride PoH2 is known.
Why covalent hydride's are nonvolatile?
covalent hydride's are volatile not non-volatile
Is ammonia metal hydride?
No. Ammonia is the main hydride of nitrogen, which is a nonmetal.
