What do you mean by "heaviest"? If you have a lot of feathers, it weighs more than a little bit of lead! There are two ways to interpret this question. One is, "Which is the element with the highest atomic weight?", and "What is the element with the highest density?"
The element with the highest atomic weight is the heaviest for the same number of atoms, and the most dense element is the heaviest element for the same volume of material.
The answer is different depending on the interpretation, so I'll give both answers.
Lead has a larger atomic weight than mercury. The atomic weight of lead is 207.2 grams per mole, while the atomic weight of Mercury is 200.59.
However, mercury is more dense than lead. The density of mercury is 13.53 grams per cm3, and the density of lead is only 11.4 grams per cm3.
So if you had the same number of atoms of each, the lead would be heavier. If you had the same volume of each, the mercury would be heavier!
See the Related Questions below for more information about the most dense elements.

What is the density of a box that weighs 190 g and the volume is 20 cm3?
Because d=M/V: d= 190/20= 9,5 g/cm3.
What is the density of mercury if 20.0cm3 has a mass of 272 grams?
Density is measured in kilograms per metre cubed, kgm-3, because a gram and a litre are both one thousnadths of their base unit, density can also be written as grams per litre. A density of 5 kgm-3 is the same as 5gl-1. A volume of 2.0 ml with a mass of 27.1 g would have a density of 27.1 grams per 0.002 litres, or 27.1/0.002 gl-1. which calculates as 13 550 gl-1, which is the same as 13 550 kgm-3.
What is the density of a rock that has a mass of 480 grams and a volume of 24 cm3?
The density of the rock is 20 grams/cm3. You can calculate density by dividing the mass by the volume.
What is the density of an object with a mass of 100.8g and a volume 144cm3?
The object has a density of 0.7 g/cm3
What is heavier 40 kilograms or 20 pounds?
The conversion is (approximately) 2.2 pounds per kilogram, so 40kg is a little over four times heavier than 20 lb.
What is the average density of mercury?
1. The chemical element has a density of 15,534 g/cm3 at 20 0C. 2. The planet Mercury has a density of 5,427 g/cm3.
Lead is how much heavier than iron?
Lead is about 20% denser than iron, but its exact weight depends on the specific alloy or form of each metal. However, lead is generally heavier than iron.
Mass of Mercury?
The density of the metal mercury (liquid) is 13,534 kg/m3 or (liquid) 13.534 g/cm3. The correct SI measure of the density is kg/m3.
What is the density of an object with a volume of 20 cm3 and a mass of 40g?
2g per cm3
The volume of a sample of water is 20cm3 the mass of?
In order to determine the mass of the water sample, you would need to know the density of water. The density of water is approximately 1 g/cm3. Therefore, the mass of a 20 cm3 sample of water would be 20 grams (20 cm3 * 1 g/cm3 = 20 grams).
Weight of 1966 mercury 20 hp?
it is 88 pounds. That's only 40 kg, it certainly felt heavier than that when I was a kid :)
Which is less dense 20g and 10 cm3 or 20g and 2 cm3?
Just divide to get the density, and compare. 20 / 10 = 2 g/cm3, 20/2 = 10 g/cm3, so the first is less dense.
What is the mass of 7.76 ml of mercury of density 13.6 g per ml?
7.76 x 13.6 = 105.536 g At a temperature of 20 0C the density of extrapure mercury is 13,534 g/cm3 and the mass will be 105,023 84 g.
What is the mass of 1.0L of air if the density of air equals 1.2 g cm cubed?
1 Liter = 1,000 mL = 1,000 cm3 (1.2 gm/cm3) x (1,000 cm3/L) = (1.2 x 1,000) (gm - cm3 / cm3 - L) = 1,200 gm/L This is the solution per the numbers postulated in the question, but the whole situation is suspicious. That's an awfully large density given for air ... in fact, it's actually about 20% heavier than water.
What is the density of a box that weighs 190 g and the volume is 20 cm3?
Because d=M/V: d= 190/20= 9,5 g/cm3.
Is the mass of sugar 20 cm3?
No. It cannot be. Mass cannot be measured in cm3, which is a measure of volume.
Is the volume of gold 20g greater than the volume of lead 10g?
We need to calculate the volume of a metal from the density to be sure. Density of pure gold = 19.3  g·cm-3Density of pure lead = 11.34  g·cm-3The volume of 20 g of gold = mass/density = 20 [g] / 19.3  g·cm-3 = 1.036 cm3 The volume of 10 g of lead = mass/density = 10 [g] / 11.34  g·cm-3 = 0.882 cm3 Hence, the volume of 20 g of gold is slightly greater than that of 10 g of lead. =========================
