Radon is the densest gaseous element.
Iridium is the elemento with the highest density
Osmium is the solid element that has the highest density. Opposite of osmium is hydrogen which has the lowest density.

Osmium and iridium are the two elements with highest density.
If we are talking about elements here, hydrogen is not the heaviest. In fact, hydrogen is the lightest element. There are two ways of answering this question, depending on how 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. When a heavier element is discovered (e.g., element 120), then that will become the new heaviest element. Ununoctium is the heaviest element, but it is man-made. The heaviest naturally-occurring element is uranium (atomic number 92, atomic weight 238.0289). Another way to look at heaviness is in terms of density, which is mass per unit volume. Either of two elements can be considered the element with the highest density: osmium and iridium. The density of the element depends on many factors, so there isn't a single number for density that would allow us to identify one element or the other as the most dense. Each of these elements weigh approximately twice as much as lead. The calculated density of osmium is 22.61 g/cm3 and the calculated density of iridium is 22.65 g/cm3, though the density of iridium has not been experimentally measured to exceed that of osmium.
There is no element 173. The highest numbered element known is element 118, which is called ununoctium.
The highest oxidation state for an element is +7, but this is not unique to any one element: All of the halogen elements except fluorine have oxyacids with this oxidation state.
No. The element C (carbon) is a nonmetal, not a metal. It does have the highest melting point of all the elements, though.
When a period of elements are considered, the element in group 18 has the highest shielding effect.
The densest chemical element is the metal osmium (Os) - 22,57 g/cm3.
Osmium (Os): 22,59 g/cm3
A fluorine atom has a higher electronegativity than an atom of any other element.
