About 1980, the United States Postal Service detached the two-thirds of greater Oxon Hill that was furthest from Washington, D.C. and re-defined that part as a new postal designation, Fort Washington, MD.
A gallon of paint is heavier than a gallon of water. Mostly anything that mixes a solid into the water will be heavier than water. Most homes have a can of Spackle , which is a common liquid for patching drywall and it is almost twice as heavy as water. Of course,mercury is the heaviest liquid, but isn't common around the house anymore. But if you have a mercury switch for turning on your furnace, then that would be the heaviest common liquid by far. Which, I assume, discounts mercury - oil is lighter than water, so two choices would be sugar water or salt water.
Ununoctium (Uuo) (atomic number 118) is the heaviest synthetic element, although only a couple of atoms have ever been made! The most dense element is osmium (Os), which a density of 22.61 grams per cm3 (which is 22.61 times more dense than water!) That's almost twice the density of lead!See the Related Question below for more information about the most dense elements.here are two ways of answering this question, depending on how â¦ you define 'heaviest'. The heaviest element in terms of heaviest per a given number of atoms is the element with the highest atomic weight. This is the element with the largest number of protons, which is presently element 118, ununoctium.
