Nickel is [Ar]4s23d8 and so has 10 valence electrons. It is usually valence 2 though.
Nickel is used to make magnets more often than silver is, for two main reasons: 1). Silver is much more expensive than nickel. 2). Silver is diamagnetic. That means it has a weak, negative susceptibility to magnetic fields, it's slightly repelled by a magnetic field, and it does not retain the magnetic properties when the external field is removed. That means that even if silver were much cheaper than nickel, silver makes crummy magnets that are totally useless as magnets, and you would just have to use nickel anyway.
The meaning of 'element' is that there are no other materials in the substance. Nickel is an element, so it has no other materials in it.
of course it is
the formula is Ni3(PO4)2 :) The correct answer is Ni PO4, the answer shown is for Nickel II phosphate.
There were nearly 300 million 1982-P Jefferson nickels minted. One is worth 5 cents.

If there is no letter to the right of the image of Monticello on the coin's back, your nickel is worth about 15¢ If there is a small "D", it's worth $5 to $10 depending on condition. However there are counterfeits of the 1950-D coin so you should have it examined by a dealer or appraiser.

Althought this nickel is quite old, it is not so valuable. In fact it is worth only five cents. In 2006, the value listed for a 1948 Jefferson nickel MS-60 in pretty good condition was one dollar. With any coin, you need to look at a variety of figures before attempting to estimate the value. The first thing you should look at on your 1948 Jef. nickel, is that it has no D or S mintmark, meaning that it is a Philadelphia mint coin. In 1948, the Philly mint produced almost 90 million Jefferson nickels. The other thing you should look at, is the condition that the coin is in. A 1948 Jefferson nickel PCGS MS-60 (Uncirculated) is worth only one dollar and a MS-65 (Choice Uncirculated) is worth approximately $3.50. So unless your coin was purchased or traded from a collector or somebody else with the means of keeping a 60 year old coin in Uncirculated condition, it isn't worth much more than 0.005 cents over face falue.
A nickel is worth 5 cents so 3820 nickels are worth 5*3820, or 19100 cents; i.e. $191.00
