A fluorine atom has a higher electronegativity than an atom of any other element.
Iridium is the elemento with the highest density
There is no element 173. The highest numbered element known is element 118, which is called ununoctium.
Radon is the densest gaseous element.
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.
Carbon (C) has the highest melting point out of all the elements, and so, as it's in the first 20 elements, it has the highest melting point of the first 20 elements too. Its melting point is 3823K.
Fluorine. It is the most electronegative element.
In a given period, group 18 elements will have the highest atomic number.
Rows of elements are called periods. The period number of an element signifies the highest unexcited energy level for an electron in that element. Columns of elements help define element groups. Elements within a group share several common properties. Groups are elements have the same outer electron arrangement.
That would be the element with the highest atomic number but the lowest number of valence electrons.
Chlorine is a group 17 element and has the highest electronegativity among the elements given.
