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 halogon has the greatest atomic mass?
Radon, unless you count the synthetic Ununoctium. But because it is radioactive, highly unstable, and synthetic, I would discount it for now. It does however have the largest atomic mass for any known atomic substance. So, the answer is Radon.
What is the largest element in the alkali metal?
No. In fact lithium, one of the alkali metals, is the lightest metal. In terms of molecular mass the heaviest metals are the actinides. In terms of density the densest metals are osmium and iridium.
The mass of an atom usually expressed in atomic mass units is its?
Atomic mass
What is the atomic mass of silver?
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
What isotope has the largest atomic mass?
The relative atomic mass of ununoctium is estimated as 294.
What elements has the LARGEST atom?
Element hassium has the largest Atomic Mass.
What is the largest Group 3 metal?
Yttrium is the largest metal in group three. It is atomic number 39 and has an atomic mass of about 88.9.
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.
Which halogon has the greatest atomic mass?
Radon, unless you count the synthetic Ununoctium. But because it is radioactive, highly unstable, and synthetic, I would discount it for now. It does however have the largest atomic mass for any known atomic substance. So, the answer is Radon.
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.
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
What is the largest element in the alkali metal?
No. In fact lithium, one of the alkali metals, is the lightest metal. In terms of molecular mass the heaviest metals are the actinides. In terms of density the densest metals are osmium and iridium.
Which element has largest atomic mass?
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.
