Is the element with largest atomic mass always present in highest percentage by mass in a compound?
yes
What element has the smallest cation?
Element Ununoctium has the largest atomic mass. The element with the largest atomic mass that has been named so far is Roentgenium.
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 difference between atomic mass and atomic mass unit?
The atomic mass unit is used to express the measure of the atomic mass.
What is the atomic mass of magnessium?
The atomic mass of magnesium is approximately 24.305 atomic mass units (amu).
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 has the larger atomic radius Cu or Cl2?
The atomic mass of Cu is: 63.546 g.mol The atomic mass of Cl2 is: 35.453 g.mol So your answer would be: Cu 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
Is the element with largest atomic mass always present in highest percentage by mass in a compound?
yes
Is the atomic number the largest the two numbers shown in the periodic table?
No, the relative atomic mass is the larger.
Is germanium or tin larger?
Germanium is the largest of the two. It has a larger atomic mass.
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 has more mass iron or copper?
Iron has an atomic number of 26. The atomic number of Copper is 29. Therefore, the largest mass would be Copper if you had a single mole of each substance.
What element has the smallest cation?
Element Ununoctium has the largest atomic mass. The element with the largest atomic mass that has been named so far is Roentgenium.
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
