Bismuth

That would explain why my Bismuth is so heavy, lol.

Is it the more the actomic number the more dense it is?

That's not neccesarily true. Tungsten, Gold, and Platinum are all much denser than Lead but they have a lower atomic number. Also, Bismuth is actually less dense than Lead by about two grams per cubic centimeter. The list of elements denser than Pb are as follows:

Element (Atomic Number)
Technetium (43.)
Ruthenium (44.)
Rhodium (45.)
Palladium (46.)
Hafnium (72.)
Tantalum (73.)
Tungsten (74.)
Rhenium (75.)
Osmium (76.)
Iridium (77.)
Platinum (78.)
Gold (79.)
Mercury (80.)
Thallium (81.)
Thorium (90.)
Protactinium (91.)
Uranium (92.)
Neptunium (93.)
Plutonium (94.)
Americium (95.)
Curium (96.)
Berkelium (97.)
Californium (98.)

The denser elements on the periodic table tend to fall in the central portion of the table. As the f-orbitals begin to fill, the density of the elements with the full f-orbitals increases as the subsequent d-orbitals fill. When the d-orbitals are filled, the density then begins to decrease. Lead falls on the decreasing density slope as it has a full f-orbital and a full d-orbital. I believe this is the trend, though I may be wrong as I'm going by memory here.

lead ?

[b] what is the cost of lead per gram ?( in canadaian dollars )[/b] :D

Well, Pb is about 75 American cents per pound which would then be about .165 cents per gram. With the conversion rate of one U.S. dollar being equal to 1.3767 Canadian dollars, that would give a price of around .23 Canadian cents per gram. Lead is incrediby cheap.

Can you buy lead at Walmart?

go to a gun store, you can buy tons of lead bullets.

That would be a "yes" to Walmart then lol
