the answer is zinc
Promethium is so rare and so radioactive I don't thing anyone's ever collected enough of it to tell. It would, however, presumably be a silvery-gray color like nearly all other metals.
There are several advantages of NiMH batteries compared to ordinary alkaline batteries: 1. They can be recharged hundreds of time. So a single NiMH battery can literally replace hundreds of alkaline batteries over its lifetime. This saves money, results in fewer batteries being discarded, and uses fewer resources. 2. The voltage of NiMH batteries is relatively constant with use. The voltage of alkaline batteries decreases as the battery is used. For example a flashlight dims with use when using alkalines. But with NiMH batteries, it will stay bright until the batteries are exhausted. 3. Due to the low internal resistance of NiMH batteries, the voltage does not drop nearly as much under a load as alkaline batteries. 4. Also because of the low internal resistance, the capacity of a NiMH battery does not drop very much under heavy loads. This is why you can typically get many more shots with a digital camera if you use NiMH batteries rather than alkaline batteries. 5. NiMH batteries can deliver a much heavier current. Some devices, such as high power flashlights, cannot run (or cannot run for long) on alkaline batteries (at least on the highest settings). NiMH batteries are required to make the most of these devices. 6. Alkaline batteries may leak when they get old and/or are discharged too quickly. This can destroy whatever device they are used in.
No ordinary silverware is considered a pure element, because even "sterling silver", the most nearly pure grade used commercially for silverware, is only 92.5 % pure, with copper constituting most of the remaining 7.5 %.
Hydrogen! It's the lightest of the elements, the only element whose atoms (typically) contain no neutrons, and it's the most abundant element in the universe because it's the main ingredient in stars, which make up nearly all the universe's mass (as far as we know.)
By the middle of the 1800's, about 60 elements have been discover
The alphabet of every language can be used as a geometric tool. Without writing, geometry is nearly impossible.
It has metallic compounds (metal-metal), and it will also combine with nearly anything that can gain an electron (polyatomic ions, non-metals). It doesn't react very well or often due to its electronegativity.
coz they are boss creatures
Yes, the casing is nearly always made out of a polymer.
Nearly every electric car and hybrid utilizes lithium ion battery technology.
No. Magnesium ribbon is nearly pure magnesium, which is an element.
One could find information about the Chinese alphabet by using the media, such as books or websites. It also can be found by asking translators, who study the language nearly every day.
No magnets only stick to iron. (Magnets will also stick to nickel) yes tin is metal. tin is a low-melting, malleable, ductile metallic element nearly approaching silver in color and luster: used in plating and in making alloys, tinfoil, and soft solders. Symbol: Sn; atomic weight: 118.69; atomic number: 50; specific gravity: 7.31 at 20°C.
The lightest and most abundant element in the entire Universe is hydrogen. Hydrogen has an atomic mass of nearly one.

Plagioclase feldspar is a non-metallic mineral. It has 2 cleavages at nearly right angles. It is also differentiated from potassium feldspar because it contains striations. Potassium feldspar has 2 cleavages at nearly right angles.
If you need a battery, look no further than the Battery Store. They carry nearly every conceivable battery a household or business could use. Door lock batteries, UPS batteries, CNC/PLC batteries and coin batteries are only a few of their offerings. They carry batteries from major manufacturers such as Duracell, Maxwell, Panasonic and Hawker. If you need a sealed lead acid battery, they carry 2V through 12V models. You can find batteries for everything you own at the Battery Store.
