The naturally occurring element with the largest mass would be uranium. The largest Atomic Mass for an artificial element (or any element) would be Ununoctium.
Neutron stars, which are neutrons densely packed together surrounded by a thin layer of degenerate matter could possibly be considered atomic nuclei, though their specific proton count would probably not be measurable.
These, at perhaps 12 miles in diameter, would of course be larger yet.

What is the atomic mass of the element Ne?
Neon is a non meta element. Atomic mass of it is 20.
What element that has an atomic mass of 14.007?
Nitrogen, element 7, has an atomic mass of 14.0067, rounded to 14.007.
What does the atomic mass of an element measure?
Atomic mass of an element measures the mass of that element on a molecular scale, taking into account neutrons and protons, which weigh approximately 1. Electrons are negated. Atomic mass is also the mass, in grams, of 1 mole of that element.
Which element has an atomic mass of 200?
Mercury has an atomic mass of 200.
What element has an atomic mass of 50.942?
Vanadium is the element that has an atomic weight of 50.942.
The largest atomic mass?
The element with the largest atomic mass is oganesson, which has an atomic number of 118 and a standard atomic weight of approximately 294. This synthetic element is highly unstable and has a very short half-life, making it difficult to study.
What elements has the LARGEST atom?
Element hassium has the largest Atomic Mass.
Is the element with largest atomic mass always present in highest percentage by mass in a compound?
No, the element with the largest atomic mass is not always present in the highest percentage by mass in a compound. The percentage by mass of an element in a compound is determined by its atomic mass and the total mass of the compound. The composition of a compound can vary based on the number of atoms of each element present.
Which element has the largest atomic mass in the noble gases?
Radon
Does The element with the largest subscript in a formula have the largest percent by mass in the compound?
Sometimes, but not necessarily: The largest percent by mass in a compound is that of the element for which the product of the subscript and the atomic weight is highest. For example, there is more carbon than hydrogen by mass in CH4.
What is the atomic mass for magnesiam?
The atomic mass of magnesium is approximately 24.305 amu (atomic mass units).
Which element has the atomic mass of 126.9045?
The element is Iodine (I). It has an atomic mass of about 126.9.
What element has the highest atomic mass?
The element with the highest atomic mass is Oganesson.
What is the largest element boron carbon oxygen or nitrogen?
The largest element among boron, carbon, oxygen, and nitrogen is oxygen. It has the highest atomic number and atomic mass compared to the other elements listed.
Which element has a greater atomic mass A or B?
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an element’s isotopes based on their abundance in nature.
What element has an atomic mass of 131?
The element with atomic mass 131 is Iodine (I)
